This is fix for bug #309: http://www.openchrome.org/trac/ticket/309
which is regression after RandR branch merge.

I compared all registers operations between legacy code and new code
and found important difference. Posted patch copies lacking register
operation from legacy to new modesetting code.

It fixes mode switching on my P4M890: I made a lot of xrandr
resolutions switches without problem. However I have no idea if this
won't cause any problems on other chipsets. For me it looks pretty
safe, even more as it was used for quite a long time in pre-merge

I've to complain about sth :) Using vgaHWPtr is real pain for
debugging. I had to make wrapper for all registers operations to print
them in log.
