Some more ideas for software power savings:
1.  Power off each peripheral not in use.  Control on the fly.

2.  Enter idle mode in your RTOS idle loop.  Idle mode stops the processor 
clock, but peripherals stay up.  This is a similar to power consumption of a 
DC light controlled via PWM.

3.  If app can afford 4096+ clk dly post interrupt, enter Power Down in RTOS 
idle loop.  Wakeup condition via external interrupt.  Be sure to read the 
Wakeup Timer section in UM_LPC21XX_LPC22XX_2.pdf
