Hi,

I'm doing the same thing and I'm still trying to figure out how to
wake the unit up. I think 
you maybe missing something. My sequence in powering down is this:

set EINT0 to port 16 (PINSEL1) (I'm using EINT0)
EXTWAKE = 1
PCONP = 0 (all peripherals off)
PCON = 2

I already tried generating a low on EINT0 to wake up and nothing's
happening. I'd be glad 
to know your progress. :)
