====== IBM Thinkpad T400 ======

===== Hardware Overview =====

  * CPU: Intel P8700, 2 cores
  * Wireless: Intel 5100
  * Graphics: Intel GM-45
  * Bluetooth: Yes

===== Notes =====

  * acpi_ibm controls brightness, light control correctly, complete with button presses
  * volume control buttons control the application with focus; not the global sound mixer
  * minimum power consumption with low backlight and wifi disabled: approximately 11W
  * drm2 supports the graphics hardware with hardware %%OpenGL%%
  * The front-panel connector for the headphone audio is actually a separate device - and is actually device '0'; so 'sysctl hw.snd.default_unit=1' is needed to route audio to the speaker.

===== TODO =====

  * Upload devinfo -v
  * Upload acpi table
