Ah, I see. I just compiled a new vanilla-2.6.12-rc2 with those options
inside the kernel, but no change.
So I'll try to use them as modules.

Mine looks similar. Despite the Identifier, VendorName and BoardName
which are not important for correct working, right?
IMHO the only important lines are BusID and Driber, which are the same.
What modules do you load?
I load these:
--------------------------------------------
Section "Module"
Load "bitmap"
Load "ddc"
Load "extmod"
Load "int10"
Load "record"
Load "vbe"
Load "dbe" # Double buffer extension
SubSection "extmod"
# don't initialise the DGA extension
Option "omit xfree86-dga"
EndSubSection
Load "type1"
Load "freetype"
Load "glx"
# This loads the DRI module
Load "dri"
Load "GLcore"
EndSection
--------------------------------------------
Actually I can't tell exactly how this combination of modules came
together. But most of it was there already or is derived from some not
really understood manuals. :)
