If you're on amd64 it looks like suspend/resume needs more work - the 
#ifdef to reject requests was only put in a few months ago - see 

If you're running i386 then you should start by enabling all the ACPI 
debugging by putting 'option ACPI_DEBUG' in your kernel configuration 
and following the instructions in acpi(4) and 
  People on acpi@ might be able to help too.
