Sleep/wakeup works with a modified arch/ppc/platform/pmac_sleep.S (bl reloc_offset was missing which you send later). I still have a strange problem with some programs started in init-Scripts. For example if I run dbus on bootup and directly after that go to sleep and wake-up again my ibook doesn't resume harddisks leaving the following last messages:Hi !
There have been various reports of issues with sleep among others on iBook G3 equiped with the 750FX processor. Also, the cpufreq code on these so far didn't change the CPU voltage, which limited the actual power saving at low frequency.
I have uploaded various patches that should help fix these issues. Those patches are all against current linus bk and they should be all applied in the order below.
I would really appreciate some tests as I don't have access to any of these machines. I need to know if cpufreq works reliably with those patches and if the new voltage control makes any differnece on battery life (check power consumption in /proc/pmu/battery_*/current when running on battery) and I need to know if the patches are improving reliability of sleep/wakeup.
The 4 patches can be found at these URLs. If you had earlier versions of some of these, those patches replace them:

Please, let me know asap,

If I disable dbus (stop it) and go to sleep, wakeup - no problem. Sometimes it is even enough to just only restart the
daemon.
I'm not sure about cpufreq. I used to run the cpufreq daemon. With this program I realised three possible frequencies on my ibook: 400, 462, 700 MHz. Using powernowd or directly the userspace governour gives only 400 and 700MHz. So maybe there is something wrong here, too or this specific CPU/ibook does only support 2 states.
