[Vaio SZ5MN] Unable to Power-off

I am runing a FreeBSD 7-STABLE i386 box on a Sony Vaio VGN-SZ5MN and I
cannot totally power-off my laptop.
When I switch to the acpi state 5 (halt, shutdown) everything
*seems* to work well. The OS shutdown correctly but after displaying :
"Powering system off using ACPI" (/sys/dev/acpica/acpi.c:1678)
the laptop remains powered (CPU cooler running, LCD display on), but
does not respond to any key. So I must unplug the battery and the
power cable to shut it down.
I have already sent a message explaining my problem on this ml:
But actually I am looking for some help to solve it. The fact is that
every other OS that I use, OpenBSD 4.3, NetBSD 4.0 and Linux 2.6,
manage well the ACPI (at least power-off and reboot).
I have look at the Freebsd ACPI implementation and code. But I have a
actually no idea from where the problem could come.
Regarding that all those OS are using almost the same ACPICA code I
guess that the problem should not be very complicated.
Finally, should I post a PR?
Thanks in advance,
