 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.
