[PATCH 1/3] sstfb: fix pixclock setting on Voodoo 1/2 cards
From: "Antonino A. Daplas" <adaplas@gmail.com>

From: Ondrej Zajicek <redacted> 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 .
