Why try PLL 135?

AFAIK the RAGE PRO LT PLL upper limit is 230 Mhz. This means that the PLL locks
best in the range 115-230 MHz. Outside this range, the PLL may not lock to the
specified frequency. If you use PLL 135, atyfb will assume the PLL locks best
in the range 62.5-135 MHz, which may cause screen unstabilities.
