That might be a bit more than I'm willing to swallow right now :-) I'm
actually quite busy otherwise... anyway, I'll have a quick look just in
case but don't get your hopes too high up on that one.

Let me know if you find a test case for the cirrus HW cursor, I'll have
a look at older X DDX on my side, or some other OS that might make use
of it (I tried Haiku but that didn't seem to have a problem so I suspect
they just do standard VESA).

Cheers,
Ben.
