I just picked up an X220 and have been trying to get FreeBSD running well. Some tips ichsmb acpi_video (attaches but doesn't work) aesni coretemp powerd is a must, these processors seem to be designed to run very hot unless throttled. Somehow my C3 state disappears when on AC, I think that's a bios setting? acpi_ibm needs "LEN0068" added to the list of ibm ids at the beginning of /usr/src/sys/dev/acpi_support/acpi_ibm.c...I'd write a patch but that machine is in a world of ports hurt right now :). With this many of the sysctls and leds work, still no brightness (w or wout intel DRI from Konstantin...thanks Konstantin!!) sleep/resume work, but screen is off after resume and cannot be awakened (even w/ dpms and or acpi_video). I did have some issues with an Intel 6250 Wifi+Wimax that are fixed by the patch that was in the wireless list a while ago. Matt
