I aim to please :)

Just bear in mind that neither of these things impact significantly on
the Glamo bandwidth limitation, which is the thing that most seriously
limits our graphics performance (by a HUGE margin).  And since we
barely make use of Glamo's acceleration features, it doesn't add up to
much of a change.  Still a step in the right direction, though.  I
think my FR runs a bit more smoothly with these patches, but maybe I'm
just being optimistic.

It occurred to me that the Glamo-accelerated mplayer should work a whole
lot better with the FIFO patch, and even better still if someone made it
use DRI/DRM.  Anyone up for an interesting project? :)
