I've been googling, but can't seem to find a definitive answer... Can
I install 32 bit Ubuntu on a 64 bit Xeon machine?

Specifically, in case it matters:

Supermicro MB X7DBE
2x Xeon E5430 2.66GHz Quad Core

I don't actually know anything about xeon but i dont see how it would differ from installing 32 bit Ubuntu on any other 64 bit machine, so i would say it should work just fine but you might wait for someone more familiar with Xeon.

Absolutely. Xeon is just a designation that Intel gives to it's
'Enterprise' (or server level) chips. It generally has much more L1 and
L2 cache on the proc to make it faster.

Now, if it's Itanium, that's a whole other can of worms. Itanium is
/not/ an X86 architecture and you need specifically compiled binaries
(and distros) for the Itanium.

It differs because modern Xeon's have a 32-bit instruction compatibility
(something that was pioneered by AMD with the Athlon 64). Prior to
that, "every other" 64-bit cpu needed binaries compiled for that cpu
architecture. (My memory is at a loss to tell you which other 64-bit
architectures still in production this applies too. I can't keep this
stuff straight anymore.)

Works on my Mac Pro (I intended to install the 64 and screwed up).

I dont see why not. your only limit will be the 4GiBs or RAM for the all system (central RAM, disk Cache, GPU RAM, etc).

Just a note from somebody who runs 64 bits..

Getting applets to work can be a bit painful. I still don't have Java
Web Start working correctly. There are other non-free apps for which
there isn't a good 64 bit version available.

Just checked back and I see many more responses. We have a couple
research machines. Both are 64 bit machines, one AMD and now one
Xeon. The AMD machine is running 32bit and I wanted to be sure I
could have compatibility between the two. Currently I have 64bit
installed on the Xeon machine and we're testing it out. We may end up
installing 64 on the AMD machine as well.
