Script for vesa & nouveau & nvidia drivers ??

Hi;

I am trying to understand the relationship between the three video
drivers, vesa | nouveau | nvidia, so I can write a safe script to
substitute one for the other.
_______________________________

My situation is:

I have the 2.6.29.6-217.2.8.fc11.x86_64 kernel installed and I am
waiting for the latest nvidia driver to go with it.  I want to create a
script that will substitute the xorg "nouveau" module for the vesa in
my /etc/X11/xorg.conf file until the proper nvidia driver can be
installed.  

I have already made the substitution manually for the
2.6.29.6-217.2.8.fc11.x86_64 kernel and everything is working fine.
However, I want an universal script that will handle future kernels and
drivers.

I want the script to work from the command line; not as an init/rc.local
script.  I figure it is safer to keep the vesa driver as default unless
I consciously decide to use nouveau. (Just an explanation -- I know how
to do this.)

Questions:

What I am not sure about is, if I make the substitution of nouveau for
vesa, when the nvidia driver is ready, will it be pushed or detected by
kmod-nvidia?  Also, if I run the script on xorg.conf, will xwindows
still make a xorg.conf.backup file that contains the original vesa.  I
want to easily be able to get back to the default vesa configuration if
need be?

("kmod-nvidia is a meta-package without payload which sole purpose is to
require the nvidia kernel module(s) for the newest kernel to make sure
you get it together with a new kernel.")

My objective is to end up with the nvidia driver.  I just want to
substitute the nouveau driver for vesa until the nvidia is ready.

If you have any guidance or gotcha's that are worth mentioning before I
write such a script, your wisdom would be appreciated.
