[Xorg-driver-geode] AMD Geode on Freebsd UPDATE, suggestion worked!

[Dhimant Bhayani]

One of the problems around DDC is that not ALL bios support
this feature. Behavior is similar to what is described below.
I don't know the exact sequence but my team was able to boot 
in text Mode and than 'kill' ddc probe and than run startx.

Booting in graphics mode always hanged the system in DDCProbe
Routine.

Ouch - I see why.   Mia culpa.  Try the attached patch.

Looks like 8 bit according to the log.

You're not really loading a vesa driver here - you are loading
VBE routines
for probing DDC, which obviously was successful.  Your log shows
the same
sort of VGA interaction that we would expect.

Avoiding acceleration doesn't really affect this one way or the
other -
if VGA is detected,  then we probe - graphics be damned.  This
is why
its different then what Martin-Eric is chasing.

That would be good - I'm very worried that this is where the
problem is -
but I'm not sure how to go about fixing it.
