just for comparision with T43 ;)

T42, 2373 - 11536,4

  - full backlight
  - wifi/bluetooth are off and no modules loaded even
  - undervolted 600MHz CPU at 0.7v
  - underclocked to 64/64 MHz radeon 7500
  - laptop mode with aggressive hdd standby timeout

with brightness set to 4 (of 7), the number is 9924,97

thanks, Alex
