Linux - Problems updating NVidia driver

So I decided to up grade to 0.19 of MythTV. I downloaded the source, configured and discovered I couldn't compile with firewire cable box support without libavc1394 greater than or equal to version 0.5.0. And of course, I couldn't easily find this particular libary. And I decided it might be easier if I was running an updated my system, so I went with the notorious yum update which updated my kernel to 2.6.15-1.1831_FC4 which, of course, killed my nvidia driver setup because nvidia refuses to open source their drivers which requires barely Linux literate geeks like myself to run their installer every time we bump our kernel up.

So I downloaded and installed my kernel sources and ran:

./NVIDIA-Linux-x86-1.0-7676-pkg1.run --kernel-source-path=/usr/src/kernels/2.6.15-1.1831_FC4-i686


And rebooted, and it didn't work. /var/log/Xorg.0.log says that it "Failed to load the NVIDIA kernel module". modprobe didn't know what nvidia was. lsmod didn't know either. dmesg showed nothing about it. I did a lot of googling and came across this message which indicated someone with a similar problem had noticed there were multiple copies of nvidia related object files in his /usr/X11R6/lib/modules/drivers/ directory and that removing them and re-running the installer and editing my /etc/modprobe.conf to the following:

alias eth0 e100
alias snd-card-0 snd-ice1724
options snd-card-0 index=0
options snd-ice1724 index=0
remove snd-ice1724 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modpro
be -r --ignore-remove snd-ice1724
alias char-major-81 cx8800
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
alias ieee1394-controller ohci1394
install ohci1394 /sbin/modprobe --ignore-install ohci1394; /sbin/modprobe raw1394

# all wonder remote

alias char-major-61 lirc_atiusb
alias lirc_dev lirc_atiusb
# nvidia kernel module
alias char-major-195 nvidia
#alias nvidia nvidia-1_0-7676

solved my problem. Your mileage will probably vary, but its something to try.

Oh, and I still haven't gotten firewire working with MythTV.
