I installed FreeBSD 6.1 on my corp laptop tonight. The following are notable:

• acpi_ibm doesn't appear to read much of anything useful. hotkey values work. Little else
• cpufreq works
• wacom stylus input magic works via X 'wacom' driver. Shows up as /dev/cuad1
• ath0 works
• bge0 works
• sata works
• Tablet buttons (rotate/tools/esc/enter/ctrlaltdel) are received by X (viewable by xev(1))

wacom was not properly calibrated initially. Guess-and-check method of screwing with calibration values made everything happy.

I'll post configs and other notes later. Naptime.
