Sorry for chiming in here, i?ve passively followed the discussion. If you produce patches for a 3.14 kernel that solve this issue:
http://lists.freedesktop.org/archives/dri-devel/2013-November/049185.html (thereby enabling AGP mode on mac mini G4?s, should still be quite a few of them around) you can register me as a happy tester. My "uptime" with a powerpc AGP system is about two minutes :-) (although the system behaviour has changed somewhat with more recent kernels from a complete lockup to an endless loop).
