I'm a bit late to the party with two things:
- The bsd ring is similarly broken and
- we can easily wait for a few msec (probably not when running piglit
  though) here, so busylooping is imo not appropriate.

I kinda prefer Chris' approach of sticking with irqs, but backing it up
with a timer in the msec range. Can't find that patch though atm (iirc
it's in bugzilla somewhere).

Cheers, Daniel
