I am trying to do something similar with an LPC2148. I have it using about 1.8
ma (incl voltage regulator) in sleep mode and around 20ma active at 12mhz. At 60
mhz it uses around 60ma. I this is not bad for my application. I may be able to
do a bit better, but as yet I have not been able to get the uart working at the
lower clock frequency to help debug the code.
You will have to add whatever each of the peripherals require. I didn't see
those numbers but I didn't look very hard.
The mA/MHz numbers are while executing from flash:

I am in a process of selecting a Cortex-M3 micro for a new project.
One of the criteria is lowest possible power consumption in run mode.
So far I was able to determine (based on manufacturers specifications) the
following values for uC families:
EFM32 (Energy Micro) - 0.18mA/MHz
Stellaris (TI) - 0.56mA/MHz
STM32 (STMicroelectronics) - 0.625mA/MHz
SAM3S (Atmel) - future device - 1.15mA/MHz (???)
LPC1768 (NXP) - ???
I am not able to find the value of mA/MHz for LPC1768.
Can anyone point me to it or similar indicating power consumption for run mode
