I just picked up an X220 and have been trying to get FreeBSD running well.
Some tips

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).
This is probably another driver bug. Try kldunloading and kldloading
your wlan driver to see if that works, and/or start stripping your
kernel of unnecessary options until you find the magic formula for
what works, and just apply that to rc.suspend // rc.resume and file a
PR for the driver bug if there isn't one already.

Driver bug in wireless can leave the screen off?
I can for instance type reboot and reboot etc.
I also noticed that acpi_video attaches, but nothing works. Looking at
AML it appears that the correct "hooks" are present, but lcd0 shows as
inactive and does not go to "1" in sysctl.
ibm_acpi lcd_brightness hooks do not work either.
debug.acpi.reset_video does VERY bad things, involving a reboot loop and
flashing thinklight
Is there anything else I can do to turn the damn thing back on?
Any other logging or things to look at?
I will try a minimal kernel shortly.
Thanks,
Matt
