Hmm - don't spend too much time in the bowels of the X server, this doesn't
look like the same failure from before.  In fact:

(II) GEODE(0): VESA VBE DDC read failed

That looks like a good old fashioned "DDC doesn't exist" sort of failure -
either your monitor isn't returning the good stuff, or the hardware DDC
lines aren't hooked up or the BIOS isn't using the DDC.

If you had the problems from before, then you would be crashing X or
just flat out hanging.  Bart should chime in here, though, he is more
familiar with the DDC subsystem.
