I can confirm this problem. IT appears to be a kernel issue. The fn keys for brightness, bluetooth and wifi work fine for me. fn-f4 (suspend) will only work if I do "modprobe -r thinkpad_acpi" as noted above. The issue also occurs if I switch to a console, so it would appear to be some kind of acpi/kernel problem rather than with xorg event handling.
