For instance, there are per-interface RFKILLs in the X220 ACPI that aren't really exposed in our acpi ibm, among others (kills for GPS, WWAN, and I think WiMAX). I was hacking on this and the brightness, had to put it down for a moment. I might get a chance to look at some of this stuff later today. The brightness control will not work, as far as I know on Linux their thinkpad acpi driver skips its own brightness controls on these models in favor of ACPI control. So far I was able to make a patch for acpi_video that does work (the wrong way, by using \_SB.PCI0.VID for attach, but making the brightness calls to \_SB.PCI0.PEG.VID) and was testing a patch from John Baldwin to see if I could get acpi_video to attach directly to the PEG device.
