As Rui suggested, add 'powerd_enable=YES' to rc.conf for that.  However 
it does seem a bit odd that hw.acpi.thermal sysctls aren't showing up.

If you turn that on you may get some more clues in /var/log/messages.  
ie hw.acpi.verbose=1 in /boot/loader.conf

I don't recall ever seeing a battery.state of 7?  When fully charged my 
Thinkpad T23 shows state 0, battery.life 98 to 100 (%).  If your battery 
is ok you should get at least 1 hour on battery, maybe 2 or 3 hours, so 
that does look like a problem .. whether hardware or ACPI I can't guess.

Is this a new machine?

Have you tried loading acpi_toshiba(4) ?  Try kldload acpi_toshiba, if 
it's of any help, put acpi_toshiba_load="YES" in /boot/loader.conf

cheers, Ian
