ati driver (fglrx) and no 3d acceleration

[RoboticGolem]

You'll want to change this value from this:

    Option "UseInternalAGPGART"         "yes"

to this:

    Option "UseInternalAGPGART"         "no"

Then, in theory it'll use the agpgart that the kernal has loaded for
your mb instead of the one for the old mainboard that was compiled
with the ati driver (I think)  Either way, Bob and I have the same
idea.
