[Pm-utils] Restore state around suspend/resume

[Dan Nicholson]

Hi,

Currently, suspending the computer via pm-suspend (as done from HAL),
causes the ALSA state to be stored and restored via alsactl. Here's
what the hook looks like:

http://cgit.freedesktop.org/pm-utils/tree/pm/sleep.d/65alsa

Is this still necessary on recent kernels? Is there a list of drivers
which properly maintain state across suspend/resume? We're trying to
cut down on the amount of work done in userspace which slows down
suspend cycles.

Thanks.
