On the same hardware FreeBSD 6-stable with INVARIANTS panics with
   panic: trying to sleep while sleeping is prohibited
when waking up from an APM suspend. Without INVARIANTS everything seems fine.
I tried to take a dump, but for unknown reasons savecore does not find one
(and savecore -f brought up an older USB related panic that had  
already been saved).

I have no experience with FreeBSD 5.x.
