Unfortunately I am not using the pm patch, because I am stuck at
2.6.30-rc8. This is because it is the last place I have usb host
working. I backported the necessary changes and pm wasn't an absolute
necessity, basically equivalent to not compiling in PM. I basically
used nearly every related patch after 6-6-09 - the 32 mmc patches.
