Works on the 17" G4 (5,5). I had to add asm/suspend.h manually but I
suspect that's just due to confusion in my repos.

The patch clashes with swsusp changes to radeon_pm.c (just remove the
if (!state == PM_SUSP_MEM) return 0; at the start of radeon_pci_suspend
before patching), I've disabled swsusp for the first try. A test with
swsusp enabled is next.

Thanks a whole bunch - I had even added swsusp support to pmud to work
around missing sleep. But sleep is so much faster :-)
