You'd just have /dev/mouse in your XF86Config fle and would have to run 
a script to change where the symlink points to, depending on the kernel 
version that you are running. Personally, I just log in as root, run mc, 
then edit the XF86Config file and change the line to the correct mouse 
device. On my system, /dev/mouse is a symlink to /dev/psaux. I use 
/dev/psaux instead of referencing the /dev/mouse symlink.

I was thinking that you might be able to come up with a script that 
echoes the computer that you are running and sets the symlink /dev/mouse 
to point to the correct real device driver. I guess you could echo the 
output of "uname -r" and change the symlink based on the output. (2.4* 
or 2.6* or something)

About the nvidia driver locking up X, did you rpm -e the mesa drivers 
before you installed the nvidia drivers? I have a computer that has 
nvidia video. I never tried to put Linux on it because of the closed 
drivers though. I seem to remember that the mesa drivers supplied with 
XFree86 conflict with library files or something. You might want to 
browse the list archives for the details. I believe it was discussed at 
length a month or so ago.

Good luck on getting the nvidia driver to work.
