I agree.  Also, they dropped 2292 in the prototype that someone else
had lying around and meets requirements of this board.

On my board max is 230400 baud with PLL disabled.  If I enable PLL and
set multiplier to 4 (all else being same) max is now 921600 baud.

So the smallest divisor works out to be to be 4 in both cases.  Does
this mean UART baudrate limit is CPU/16/4/VPBDIV?

Suggestions anyone?
