You could also think of it as an interesting learning experience lying
ahead of you...

I think we can make this significantly less painful than having a root
canal without anesthetic.

I think the problem may be that your version of the kernel lacks the
kernel part of the graphics drivers which is needed by Xorg. Essentially
you have three options now:

1) Switch to the "vesa" driver. There is a good chance that it will work
   because it uses a generic way to address the video hardware without
   any fancy tricks. The downside is that there will be no hardware
   accelerated graphics rendering. This might be acceptable if you
   mainly intend to do things like word processing, spreadsheets, etc.
   If you need anything that uses 3D rendering then you can more or less
   forget about vesa.

2) Upgrade your kernel to the latest version that is available as a
   backport for Sarge. This may or may not work and it also involves a
   udev upgrade. You can of course also try to compile a newer kernel
   yourself. Overall it might be easier to just upgrade to Etch and be
   done with it, though.

3) Remove Xorg and reinstall XFree86. You can probably trigger the
   removal of Xorg by telling apt(itude) to purge package libx11-6. This
   should take the rest of Xorg with it. With aptitude you could also
   use something like

   aptitude --purge-unused purge '~i(~dxorg|~dx11|~dxfree)'

   This command asks for the purging of everything that has "xorg",
   "x11" or "xfree" in its package description. (I am not 100% sure if
   Sarge's version of aptitude already supports this type of pattern

I will keep the most important parts of your xorg log in this message,
just in case. It does not give me any more ideas, but maybe somebody
else notices something. I am a bit surprised that it does not seem to
indicate complete failure to start X.
