What response did you get from the Debian Kernel Team
<debian-kernel(at)lists.debian.org> ? I see that only one member of
the team responded to your bug report, so maybe another member or
some other knowledgeable subscriber to that list could be of help.

What do you get from running 'hwinfo --framebuffer' ? The hex
equivalent of decimal 791 is 0x317 -- did you try that as well?

Hi Hugo

If it is of any help, 791 works for me with the Debian 2.6.25 kernel. I
had been using 773 (256 bit colour) as I had no need for anything else,
but having read your post, I have changed it, rebooted and it appears to
be working.

Actually I got the same error with the indication of a bad mode. so I
paid attention to the mode tried, and it was the decimal conversion of
the hex I wanted... To correct things all I needed to do was to write
the mode in hex mode, for example 0x317. That worked out for me...

Indeed. I can try posting to the debian-kernel list again, I tried that
before and got no answer.

Too bad, but I try vga=0x0317 or vga=0x317 and I stll get "undefined
videomode" with 2.6.26-1-686. But with 2.6.26 they get results.

Bummer. Just for sanity's sake, did you try "vga=0x317"?

Yes. Same error.

But I did something interesting: I downloaded
http://cdimage.debian.org/cdimage/daily-builds/sid_d-i/arch-latest/i386/iso-cd/debian-testing-i386-netinst.iso



And *that* has linux-image-2.6.25-2-686_2.6.25-7_i386.deb which also
gives me the error. So now I will use the installer and install whatever
it wants to install and see what it brings me.




You guessed it: "undefined videomode"!

Stay tuned.

But I did something interesting: I recompiled 2.6.26-1-686 but changed
to .config file to what I use with my homerolled kernel. And guess what:
vga=791 works!


The problem lies in the .config file that Debian uses and apparently my
hardware. Something that Maximilian Attems pointed out in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=481063:


...
please enlighten us on the .config changes.
we are *not* carrying any fb specific patches.
...

So now I have to go item by item and investigate the diff in .config
files, which is vast because with my .config the kernel compiles in 12
minutes and with the Debian .config it takes 1 hour + 20 minutes!
