rivafb: fix initial brightness

rivafb: fix initial brightness

[Guido Guenther]

Hi
this is the rivafb equivalent of
238576e12fef1d52751c6e08db2d0bdb0e248caf. It fixes rivafb having a
default backlight brightness of 0 (no picture at all) on a PBook 6,1.
Since this is a regression over 2.6.20, can this go into 2.6.21?
Cheers,
