As for nVidia taking the latter issue seriously, I'm not convinced that the fault lies with driver: 6629 worked fine for me up until a certain point, after which 6629 and later drivers would freeze up eventually. I hadn't touched Xorg's config, so nothing changed there.
The thing I'd like to point out is that games work when there's NO AGP SUPPORT. AGPGART and NVAGP both crash the same but no agp support is rock solid with lower framerates.
