Has anyone got the commercial NVIDIA drivers to work on the FC2 kernel SMP updates 2.6.6-1.427 or 2.6.6-1.435? I got them to work in the orginal 2.6.5-1.358 SMP kernel by taking the kernel src rpm and rebuiling with the nostack patch removed. I did the same for the 427 and 435 kernels, but the machines locks up 0 to 10 seconds after starting X. Sometimes even on a -probeonly. I have not tried a UP kernel yet.
