Lowlights: it's broken.
I get millions of messages like:
...
[ 8482.000414] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck
timer elapsed... render ring idle [waiting on 30938, at 30938], missed
IRQ?

and everything is very choppy. I assume it's the power saving thing
that broke again, but that's just a total random guess, I have nothing
to actually back that up with.
It worked fine after boot, but those problems began at 8287.139375
(about two hours after boot - it may have coincided with screen saver,
but who knows?) and have been happening constantly since. The machine
is not really usable, I'm writing this with annoying 2-second pauses
every once in a while.
This is a regular Core i5-670 with up-to-date Fedora-14, fwiw. Not my
sandybridge.
