Do you have any other modules on FreeBSD to make it work?
I've seen a few similar reports on freebsd-current ML a few months ago,
but somehow can't find single "it works now" report there. Maybe it's
time to look at the changes in FreeBSD's acpi code.

Probably this is not it, because your laptop looks like completely
locked up rather than just the screen, but have you tried
`sysctl hw.acpi.reset_video=0' before suspend?
