Yes, that's exactly what happens. By default I get a horrible 1400x1050
resolution and a black border around the desktop. I'm pretty sure vesa
doesn't support anything higher so I'd definitely need radeon or fglrx.
Declaring depth or resolution by hand in xorg.conf doesn't change anything.
Everything is pointing to an hardware incompatibility.

For good measure the output of xrandr:

Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1050
default connected 1400x1050+0+0 0mm x 0mm
   1400x1050      75.0*
   1280x1024      76.0
   1152x864       76.0
   1024x768       76.0
   800x600        73.0
   640x480        73.0
   720x400        71.0
   640x400         0.0
   640x350         0.0
   512x384         0.0
   320x240         0.0
   320x200         0.0

On the distros it does work xrandr gives a "DVI connected" and of course the
native 1920x1080 resolution.This is really frustrating because most
older (i.e. stable) distros don't work with this hardware. Only those on the
bleeding edge do.
I think the only way to fix this is to use a newer kernel and xorg?
Should I compile them myself, use the testing repos or upgrade to squeeze.
Or something else? This is currently just a test system, it wouldn't matter
if I broke it and had to reinstall.
