* that opregion won't work on Poulsbo as is (even
Intel's driver doesn't implement it), so there's no way this patch can
make things any worse. On the other hand, if anyone ships an OS with
this hack *and* a native psb driver, I'm going to look sad for some
time.

This is fast enough and rare enough that it's worth making sure that it
happens in the vblank, which means doing it in irq context. The alternative
is visual corruption and potential machine crashes.

Reclocking the engine during screen refresh can cause corruption on some
hardware. Do it during vblank instead, and make sure that we're really
in vblank.

We want to perform radeon memory reclocking in interrupt context, so need
to ensure that we don't do anything that may sleep. Add an alternate
entry point to the atom interpreter that flags things appropriately and
make behaviour conditional on that.

The r520 atom tables sleep for long enough that it's impossible to reclock
memory during an interrupt. Implement this by hand instead in order to
avoid the delay.

Take advantage of Verizon's best-in-class app
exclusive hw access, thus we need
to take cs lock but also the lock which is protecting modesetting
(iirc there is one).
If a modeset results in a second display being activated, we need to
clock back up. vblank-driven reclocking doesn't work so well with
multihead.

Unfortunately it's basically a requirement for us to come up in VGA text

a small number of cases where we can't reconfigure a power

this. Changing it simply takes too long, and we drop several frames in
