I have here a Samsung P30 (first Centrino generation) with a Radeon 9200
and radeon driver in KMS mode, Kernel 3.10.11. Unblanking works normal.
I [br]arely use that machine, only keep it up to date from time to time
in case I may need it in lieu of my normal laptop. So its setup is
fairly default stage3.
