If you are not running any code prior to main, other than CRT startup:

On power up the peripheral clock is 1/4 of the clock frequency.  See
register VPBDIV.

Even if the divider is not correct you should still see a wiggle on the tx
pin.

Your code works on my IAR LPC2148 board.  I dropped the code in prior to
clock setup, and changed the baud pre-scaler to match my crystal.

My point on debug environment:
If you're trying to debug from RAM, be sure you're setting MEMMAP correctly.
If it's quicker to run code from flash and not fool with MEMAP try that.
Either way you need to have your debug environment setup correctly or
nothing may appear to run.
