For example, plugging or unplugging devices during sleep results in oopses at resume; and one time out of two, the USB ports are unpowered on resume (because the registers think they are, and linux doesn't repower them. but they're not). Both of these issues have patches available, patches that can be found there for example: http://colino.net/ibookg4/usb-ohci-fixes.patch http://colino.net/ibookg4/usb-ehci-power.patch What kind of work on these is needed so that they get in?
