Well, it doesn't work here (with current CVS), even with all
acceleration disabled (ie without XAA and without EXA).

Any idea if eventually the driver can do anything wrong here? (But I
don't think it does, since the very same driver, status as of yesterday,
works fine with XFree86 4.3, regardless whether XAA is enabled or disabled.)
