I expect the segmentation fault was related to thread local storage
bugs in RH 9. NVIDIA's drivers make extensive use of it and I
believe it is broken in RH 9. This was probably mentioned someplace
in NVIDIA's documenation. Mesa probably doesn't make use of thread
local storage so would be unaffected.

I don't know NVIDIA's release schedule or about status of
whatever functionality problems you were having (my FX5600 seems
to be working fine with NVIDIA's 4496 drivers).

Technical data from NVIDIA is unlikely.
