more vblank rework

- use a timer for disabling vblank events to avoid enable/disable calls too often - make i915 work with pre-965 chips again (would like to structure this better, but this hack works on my test system)

We currently mandate that the driver clears the summary indicator

for interrupt avoidance is rather that the driver unsets the summary

indicator before before it stops looking at the queue indicator.

In fact, the best way to get a race-free implementation of the interrupt

handler is to process the queue indicators twice; let's add a recommondation

to do that.
