s31 has AC0 and AC1 level cooling.  Please try;
 # sysctl hw.acpi.thermal.tz0.active=1
to activate AC1 level cooling by manual.

but automatically switching to AC1 is not functioning.
I think this is bug, I'll check later on.

How new is your kernel?  I added wake function to lid and
power/sleep button 7/22.

No, the most important patch in
http://people.freebsd.org/~iwasaki/acpi/s30-acpifix.sh
is DSDT fix for s30 BIOS.  Without this, you'll see 
ddb prompt on kernel boot.
This DSDT fix is not perfect, but better.
maybe vga_pci-20020228.tar.gz is too old?
# patches welcome :)

I noticed that after S3 sleep we can get correct battery status.
To get this all the time w/o S3, I think we neet hack s31 DSDT.
