I figured it out:
linux-image-2.6.26-1-686 has CONFIG_EDD=m set and I don't set that in my
kernel.

Indeed 'edd=off' fixes the problem. I wished I had checked back earlier,
wasted another month with uvesafb.
I still wonder why I don't have to say 'edd=off' with my own rolled kernel
to get vga-791 to work.
I'll close bug 481063.
Thanks for that solution!

I had the same problem, here is what worked for me:
apt-get install hwinfo
hwinfo --framebuffer
Look at the Mode lines, find the one I want:
Mode 0x0323: 1024x768 (+4096), 24 bits
convert 0323 from base 16 to base 10
put result into menu.lst kernel line:
vga=803
You don't need hwinfo to
I get the same error with 2.6.26-1-686.
Yet no errors with the kernels from kernel.org.
So I had a thought: recompile the Debian kernel with the .config I use.
Guess what: no error.
So Maximilian was right when he pointed to the .config differences.
It's in the .config somewhere.

A workaround to the problem is to use uvesafb instead, specified here:

Sorry I did not submit this under linux-2.6
I compiled the vanilla 2.6.25.3 kernel from www.kernel.org and that boots OK
with vga=791, so the problem resides somewhere within the Debian changes.

please enlighten us on
Package: linux-image-2.6.25-1-686
Version: 2.6.25-1
Severity: normal
specifying vga=791 on the grub kernel command line gets 'undefined video
mode number'
in previous kernels that never caused a problem.
