Can't help directly with the hardware questions, but (a) if you are
still within your Applecare coverage, take the thing in and get anything
that doesn't work fixed before touching the OS, and (b) you might try
Virtualbox with Centos as a guest (or VMware if you don't mind paying
for it). I've generally found the vendor-supplied native video, sleep,
and wireless tools work best on laptops and virtual machines work well
enough for the client-type things I do under Centos.

Being a mac system admin and support specialist and CentOS guy. I can say you can always try using an external hard drive to boot the Mac off of and install CentOS on that drive to play around and test out all the drivers for video card, wireless, etc...

I don't boot into CentOS but have it running in Parallels and it runs great.

I also do recommend to get your Mac repaired too, just be sure to clone your hard drive off to an external drive before sending it into the shop. Apple is known to completely erase hard drives with no warning.

Well, I have done the Apple support thing and Apple's official
position is that I have an interference problem. The fact that I
have six other laptops plus two X-Boxes, all with wireless
connections, in the same household and none of which exhibit the
problems that I have with the Macbook, is quite beside the point
insofar as the Apple Genii are concerned.

This to me is utter BS, since I can see in the log files that that
the wireless driver is arbitrarily disconnecting the link due to
"lack of activity" and then choking when trying to reconnect. There
are a host of other odd little symptoms that also lead me to believe
that it is the Apple drivers that are at the root of the problem.
For one thing, a frequent occurrence is that I get a 'browser is
offline' (in both Safari and Firefox) when opening a new tab, but
the existing tabs in the same browser instance can visit new pages
on existing connections!!?? How that works is beyond me but it
happens, often.

And it is the wireless NIC that I most need fixed. Right now I have
to shut down the Airport and restart it to clear the problems. In
itself this is no big deal, but I am just so tried of having to do
this with such an expensive piece of kit.

If CentOS does not support the wireless in the Macbook then I am
stuck with the sucker until I get up enough gumption to buy a
Toshiba. Which is what I should have done when I allowed myself to
be talked into the HP to begin with.

This is off list topic, but I have seen weirdness in airport cards on macs especially when connecting to Apple's Airport. A cheap fix is to buy a 2nd wireless access point and make sure to use that in bridged mode so it is not acting as a router and wire that to your airport base station.

I like said before trying using an external hard drive to install CentOS onto and try your wireless card and other hardware drivers. This is a free solution except for the cost of the hard drive.

That actually seems pretty unlikely, since a bazillion other people use
the same drivers... Or at least it is a quirk of your setup that
triggers the issue. Do you have wireless phones in the same frequency
range nearby? I do, and see disconnects that I think are related in my
d-link router logs but haven't seen any problems with connections being
re-established from anything including my son's macbook. Have you used
wireless in any other locations, and if so, do you always see the same
problem?

That doesn't make much sense but you are probably trying to reuse a
socket that has received a reset - browsers open several sockets
simultaneously and the others might not have been busy during the
network disconnect.

Do you mean disable the wireless NIC and re-enable (which sort-of makes
sense) or doing something to the router? If you really have to restart
the router, that's probably the source of the problem.

Hardware is all pretty much the same - it either works or it doesn't.

Or save yourself money and try a
live CD. I'm assuming that any missing drivers can be temporarily
installed like on Ubuntu.

You could also try Fedora, which is considerably more modern as a client OS than Cent 5 these days. *Obviously it will be quite similar to future releases of CentOS. *I wouldn't really want to run RHEL on my laptop as a client OS.

Understandable if you want to stick with CentOS 5 for certain reasons.
