Did you test that with any 2.6.27-rc before -rc7?

I don't think you need to revert anything. :-)

Please check if the /sys/devices/.../power/wakeup file contains 'enabled' for
the USB controller pci:0000:00:1d.7 (I assume this is the one the keyboard &
mouse are attached to).  If it doesn't, please try to write 'enabled' to this
file and retest.

Thanks,
Rafael
