It would be nice to avoid these problems.  When I asked on alsa-user
if one could get around turning off PCI bus pm, Bill Nottingham said
to ask IBM/Cirrus how to raise/lower the CLKRUN pin on the chip.  (I'm
not a hardware guy, so I don't know what that means....)

If that's the solution, would it be possible to get that info so some
happy alsa hacker can fix that?  I don't know how much of a difference
PCI bus pm makes for battery life, but I'd like to have as much pm as
possible.

Will the apm changes for the alsa-driver be contributed back to alsa?
