Import a mostly rewritten and extended version of acpi_ibm:

Browse Source 
- Restructured for easier extensibility and maintainability
- To be more uniform with the other ACPI extras drivers and to better reflect
  their actual meaning, some sysctls were moved:
    o brightness -> lcd_brightness
    o keylight   -> thinklight
    o enable     -> events
    o misckey    -> hotkey
    o avail_mask -> availmask
    o key_mask   -> eventmask
- New "initialmask" sysctl, which holds the initial eventmask
- The "wlan" sysctl is now read-only, since writing to it didn't have
  any effect
- The "version" sysctl was removed, since it seems to be the same (0x100)
  on all models I have seen
- Support for more hotkeys by the "hotkey" sysctl
- Improved support of ACPI events. Disabled by default, since it unexpectedly
  changes the behaviour of some keys. (on my T41p there are now 24 different
  keypress events that get reported)
- write support for: volume, mute, lcd_brightness and thinklight
- led(4) interface for the thinklight [1]
- New sysctls "fan" and "fan_speed" to support reading of fan status and speed
- New sysctl "thermal" to support reading of up to 8 thermal sensors
