We have some LPC2132 samples and have just modified a board so it 
should work with both LPC2114 and LPC2132.  I want to test the 
samples, but it is too risky to count on production quantities of 
2132 in January...

Pin 17,49,63 are interesting.  When using 2114, they are 
V18,V18,V18A, and are jumped to a 1.8V LDO.  When using 2132, they 
are P0.31,Vbat,Vref, and are jumped to the 3.3V LDO.  We'll also try 
it without a reset chip and only a pullup resistor on /RESET.

There are some additional GPIO changes such as the RTXC1,2 pins, the 
extra I2C port which cannot actively pull up, and the extra analog 
inputs which aren't 5V tolerant (philips_apps: is this still true in 
LPC213x?).  There seems to be no software differences necessary at 
all (but there would if we used IAP).  We'll test the new board after 
New Year.
