Did you upgrade your system properly ?
Regardless of suspend/resume support in your system, the events should take
place.
See http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information.

That's probably because p4tcc is enabled. Try adding:
hint.p4tcc.0.disabled=1
to /boot/loader.conf.

Wild guess here, but try booting with:
hint.p4tcc.0.disabled=1
hint.acpi_perf.0.disabled=1
