Um ... 

1) PWER isn't reconfigured by uboot (see above)
2) That you should try mainline uboot to avoid debugging problems with not-
mainlined patches
3) That the bug with PWER is likely in kernel, since there's an issue with 
gpio_set_wake() on PXA
4) That the CPU might not preserve PWER throughout the suspend and that this 
information might be found in the CPU manual

I was a bit terse there, sorry.
