Does the driver already work on the LOCO board? I just tested it on my
board and get no picture (neither on VGA nor on HDMI).
I got a picture on HDMI with another version of this driver and some
hacking in the clock code, but as of now this only works when a freescale
kernel is started first and rebooted into my kernel without powercycling.
There is no picture on the VGA output though and I think there is
code missing for the TV encoder.

This change shouldn't be in this patch of course.
