Hi !

This patch updates the PowerMac sleep support. The ability to sleep is now broken
into 2 different flags, one, "may sleep" is set for all motherboards that we know
how to put to sleep and wakeup. It gets turned into "can sleep" upon a call from
the video driver indicating the ability to wakeup the video card. This doesn't
deal with head-less machines, but this can be improved later. It also adds better
cache flush code, which improves stability with cpufreq as well as sleep.

This patch actually breaks sleep support until the video drivers for the affected
machines have been updated. This will come as separate patches.

With all your patches applied I'm getting an oops during wakeup inside
pci_bus_read_config_word on my iBook/G3.  Call trace: pci_set_master,
pci_device_resume, resume_device, dpm_resume, device_resume,
pmac_wakeup_devices, pmu_ioctl, sys_ioctl.

Andreas.
