[PATCH] mbxfb: Fix a chip bug? resulting in wrong pixclock
This is a workaround for what I think is a bug in the 2700G chip.
The PLL output frequency is adustable using 3 values (M, N and P. See code
for formula). The N value range is documented to be 1 to 7 but when it is set
to 1, the output frequency is lower than it should be (divided by 2), giving
unexpected results such as no sync on a CRT display.
This patch prevents N=1 when searching for the best value for the requested
pixclock.
