It seems geneally good.

However I've noticed that priority of X fluctuate a lot for unknown
reasons...

When doing almost nothing it gets prio 6/7 but if I only move the
cursor a bit it jumps up to ~29. 

If I'm running glxgears (with diret rendering ON) the priority stay to
6/7 and moving the cursor I'm only able to get priority 8.

Under load X priority goes up and it suffers (cursor jumps a bit).

IOW: strangeness!
