backlight failed after suspend to ram on IBM X40
 

Hi,
SRU Justification:
IMPACT:*Turns out some machines, like the ThinkPad X40 don't come back if you*don't save/restore this register.
FIX: The patch save and restore one more value of the register while suspending and resuming.

TEST: User on the launchpad acked the patch works for him.

Best regards,AceLan Kao.
