Success! (Except the expected things)

This is a bit of an "Me, too", but I have not seen a report on a T30, so:
> sysctl 2060 2252 0 2060 288 7 9 0 0 0 0 3738 1 48 49 50 -1 32 31 26 28

I'm still trying to track down which thermal is which. Volume,
lcd_brightness, mute, thinklight, fan_rpm, fan_status and thermal all
work. As generally reported, wlan is non-functional. I think that this
is simply that the FreeBSD wireless drivers don't have code to turn off
the radio. I suspect that the BIOS is doing the right thing and FreeBSD
is not (yet).

Thanks for doing all of this work. It looks great!
