You shouldn't need any xorg.conf at all.
At least, turning EnableAGPDMA off is probably not what you want speed
wise. Was there a reason you added that option ?
MigrationHeuristic is related to EXA, but you're asking for XAA 2 lines
above. And anyway, XAA has been removed starting with 0.3.0, so you have
the choice between EXA and no acceleration.
Try with no xorg.conf.

Try to 'modprobe via' before running X.

Also, openchrome 0.3.1 is old, you might want to try 0.3.3, which is the
latest.
