Yes, MFCd.  The reboot problem appears in Linux too so it's likely that 
it's something acpi-ca is doing or not doing.  Unfortunately, you have 
to write to pm1a/b to trigger a suspend so it's likely that the code 
does something wrong before then.  Try commenting out various calls to 
_GTS, _PTS, and all the pm1a/b writes.  Test each separately so you can 
see what each change does.  I think someone found a system where calling 
_GTS actually triggered a sleep (non-standard).
