Note that I'm having some troubles with James current mach64 bk on a
wallstreet PowerBook (mach64 LT-G). There is an endian bug in the
imageblt implementation, I don't know if the chip can be instructed
to do the endian flip, so I modified the function storing to the
fifo, that appear to work, at least with 8 bits mode ;)

But I'm having lockups, very regular. I haven't been able to figure
out why though. Adding a wait_for_idle() at the end of both fillrect
and copyarea() seem to make them disappear (well, almost, I had _one_
still once). It's weird as those shouldn't be necessary.

Maybe we should add a timeout on the wait_* functions with an engine
reset, that would be sub-optimal, but at least we wouldn't lockup the
box (if that is possible of course).

Ben.
