i have the similiar problems with my redhat 7.3 and kernel-2.4.18-5.
i just updated to that kernel from -3 so the nvidia drivers "crashed". yes that borgzilla's thread was great, there i got the help for this problem...but now there is no such thread so i need that help again.
the sources wont compile (drivers 29.60) and rpm's nether. there was some sort of tweak...it only makes error "Failed to initialize the NVdriver kernel module!"
