Re: kern/37894: azalia power management support is incomplete, buggy

As of r1.20 of arch/x86/x86/cpu.c, one can do the following:

  # cpuctl offline 1
        ^ do this for all but cpu0
  # sysctl -w machdep.sleep_state=3
  # cpuctl online 1
        ^ do this for all but cpu0

and azalia will resume properly as it does with a UP kernel.

Still not a fix, but a much better workaround than running in UP mode.
