CONFIG_USB_SUSPEND are you sure it works on all PC out there ? Only think it will make the beginners forum grow in size with threads like this "Why is my USB ... .... not working "
Maybe you can give us a good howto for making power safe ?
I guess you always have too compile your kernel any way, Just too complie for the right CPU makes it perform a lot better. Too bad xconfig and gconfig dont work out off the box.
