Mea culpa, mea culpa, mea maxima culpa.

The suspend event is in fact received.  I rebuilt with debugging on, stripped
the system and tried again.  I saw the suspend event and everything up to the 
final call into the APM bios.  Upon resume, nada.  I'm going to do a bit more 
debugging.

Oh, I have checked against the linux differences in the APM code.  The most 
evident difference is the removal of a CLI instruction from the call into the 
APM BIOS.  I haven't ripped the code all apart though.
