Hey, quick follow up... I was having the same trouble as you had before, with the Nvidia drivers killing X. When you installed the RPMs, did you modify the XFree86(4) config file, or did you just leave it as is? I tried installing a few days ago with the RPMs, and modified the file from "nv" to "nvidia", and it took about 15 minutes for X to boot, and the next time I rebooted I got a kernel panic. I think my computer hates me, linux, or both. :-p
