[PATCH 1/3] sstfb: fix pixclock setting on Voodoo 1/2 cards

["Antonino A. Daplas" <adaplas@gmail.com>]

From: Ondrej Zajicek <santiago@crfreenet.org>

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 .
