I find that when using apm instead of acpi, hibernation does work with
Fn-F12 :) So I suppose it is the problem of FreeBSD's acpi...
I do not even need apm_enable="YES" or apmd_enable="YES" in rc.conf
for hibernation to work (actually I can't have them turned on as they
complain about the nonexistence of /dev/apm). 
However, I suppose that apm does not support speed-step, so I must decide
whether hibernation or speed-step is more important for me...
