There have been other changes to the system PM code approximately at the same time. The "massive" PM change didn't really change what was done to the vidoe chip on older models (mostly _added_ new code, totally separate, for new models). I suspect for example a problem with the cache flush code in pmac_cache.S on some G3 CPUs ... There is also an old problem with AGP and sleep that is coming & going lately. Can you check if it works if you never go to X ? (That is boot in console mode, do not ever launch X, launching X and quitting X breaks the test I want you to do, then suspend/resume). Ben.
