The LPC2101/2/3 implement a fractional divider on the UARTs, just as in the
LPC214x series.

Enter in your peripheral clock and desired baud rate into my utility and it
will return a list sorted by margin of error:

You should be able to run right at 70MHz and get nearly any baud rate you
like, at least on the UARTs...
