Hi ! This is an experimental patch against 2.6.9. It concerns the ATI based Aluminium PowerBook. The nVidia based ones aren't concerned at all, and the iBook G4 will have to wait a bit more for me to get the video wakeup code right. It will add sleep (suspend-to-ram) support for these machines. It's based on various tested bits but is untested on these machines in it's current form, so let me know. Ben.
