[PATCH] fix pixclock setting on Voodoo 1/2 cards

[PATCH] fix pixclock setting on Voodoo 1/2 cards

[Ondrej Zajicek]

Pixclock setting in sstfb didn't work with my Voodoo 2 card
with ICS 5342 DAC (this DAC requires two consecutive writes
to one of its registers to program pixclock - maybe first
write merged with second).

This patch fixes bug with pixclock setting. It is against 
2.6.21-rc1 .
