    sys/dev/acpi_support acpi_ibm.c 
  Log:
  Import a mostly rewritten and extended version of acpi_ibm:
  
  - 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
