There isn't anything "above the XAA layer". XAA lets drivers hook
things at 2 or 3 different levels. It's just not documented.
Watch the LOW, MID and GC level in xaaInitAccel.c. LOW is the
documented interface. XAA builds MID from LOW, builds GC from MID.
GC is the top level. Of course, you don't have to use XAA at all
if you don't want to, but XAA is an all or nothing thing.
