I've noticed the same difference on my ancient mac mini G4 with a humble RV280
GPU. I try to boot it in AGP mode from time to time after applying some
patches, just for fun. Before i would see some GPU lockup-resetting stuff (it
always locks up after some time and never recovers) in kern.log, lately it just
locks up and there's nothing in the logs.

The patches i applied lately were

[PATCH] radeon: allow write_reloc with unaccounted buffers to cope
 with Mesa bug

https://patchwork.kernel.org/patch/4663071/

and 

drm-radeon-fix-TOPDOWN-handling-for-bo_create-v3.patch

My guess would be patch number two.
