Well i'm not sure what a good test would be.  Only started looking
at the logs and such because as soon as i enable EXA my CPU usage goes
to 80% - 100% and doesn't stop.   XAA works okay, unless trying out compiz.
I didn't think the AGP issue was necessarily related, but thought it would
be "easy" to sort out ;o)   Anyway, I won't drag you into my EXA woes.
Thanks for taking a look at the AGP issue.
