Any news on the brightness? My X220 came and FreeBSD installs and boots fine with MBR. But like you said brightness control is not working and I am stuck at max. Even with me 9cell battery, it brings it down to 5 hours instead of 8-9 with a slightly dimmer setting. P.S. I didn't have to touch anything in BIOS.
