[ltp] Power drain with radeonfb and fbcon built in

[Dan Sawyer]

Felix,

There were a couple of changes in the kernel config structure between 
2.6.20 and 2.6.23. I was never able to get either .21 or .22 to suspend 
correctly. However .23 suspends consistently. Below are relevant 
configs. Note: DRM does not work with this config.
