Acer TravelMate 341T - cannot shutdown

[Owen Jeremiah]

I'm trying to install FreeBSD 5.4 to my old Acer TravelMate 341T. It worked
flawlessly. But I'm having trouble with powering down and suspend mode.
Simply put, it won't shutdown (shutdown -p now resulting in reboot
condition) and it won't suspend (just hang in console mode).

Anybody can shed any insight?

TIA
