version 2.2.0 of the intel driver contains commit
6eecef4fed8a21dfdabef42eb69fd150b96167b2 which reverts the TV out
brightness from 0x10 back to 0x00, fixing this washed out issue for me. 
(In fact I also change the contrast and saturation from 0x60 to 0x40 for
even better results).  You can hack the 2.1.0 driver with a hex editor to
get the same results :)

Are you only seeing this issue with TV out?
