Testers wanted: amd64 ACPI suspend/resume

Heyas folks --

Thanks to Joerg, suspend/resume is now working properly for at least the 
two of us on amd64 on the jmcneill-pm branch. If anybody else could test 
it out and send us success/failure reports, that would be fantastic.
Same rules as i386 apply wrt. playing with machdep.acpi_vbios_reset and 
vbetool post as necessary.
Cheers,
Jared
