I uploaded a new version at: Here's a 3rd version. It may or may not help, as I didn't have a chance to test this one on either albook or ibook g4 yet. I added saving and restoring of a few more registers that may fix the Xv problem (or not... depends what X does at this point) and eventually some corruption problem (the bandwidth related registers weren't restored). It also adds an unrelated fix to the cpufreq code for powerbooks using PMU-based frequency switching which would occasionally cause hangs at boot. http://gate.crashing.org/~benh/albook-ibookg4-sleep-3.diff Ben.
