Or rather Axel's.

Haven't ever had to do that myself, but I haven't had a chance to try 
Axel's latest rpms yet.

Yes, mostly.

Indirectly, because Axel is trying to work around some of the hackish 
stuff nVidia has done in the past.

You should definitely report this to Axel also.

Red Hat tested plenty. But they do NOT officially support the use of 
proprietary binary-only drivers like those from nVidia. The problem 
really isn't Red Hat and/or NPTL, it is the way nVidia haphazardly 
wrote their drivers, doing Very Bad Things replacing libraries 
willy-nilly from XFree86-Mesa-libGL. nVidia is aware of their 
transgressions, and they are working with Mike Harris (the Red Hat XF86 
maintainer) to produce cleaner drivers that will actually work going 
forward. There has been quite a bit of discussion on this front on the 
various Red Hat/Fedora mailing lists recently.
