    Sorry for the delay. Tried loading acpi_video in /boot/loader.conf. 
After having a terminal, I checked the available mibs with sysctl -a | 
grep acpi.video. Only get hw.acpi.reset_video. The man page didn't throw 
the waited ray of light :)

   I also tried suspending from the terminal, without X's running. I 
tried vbetool (dpms off/on and post). I wasn't brave enought to try 
vbestate save and restore.

   Finally I decided it was time to use all the arsenal available :) so 
I decided to remove everything not necessary. So usb and friends, 
firewire, cbb and pccard, if_bge, if_rum, snd_hda and nouveau were 
removed from the kernel. Tried going single user mode, remove them and 
acpiconf -s 3. Guess what happened :)

   Checking messages doesn't show anything unsual. But if you want them 
or if I can try others things to debug, let me know.

   Greets,
