right now, the only module I removed(which was causing my s2ram pause)
is isight_firmware.ko.(need to look into why this is)
after that s2ram works good.

Now the usb issue, seems I see this every time I s2ram.
there is an external usb mouse, but makes no difference if it's connected,
or disconnected..still see the root hub lost power.
(maybe the machine is getting old: macbook pro 2yrs old)
