Video card change on working system

[Mike M <linux-support@earthlink.net>]

I am going to change my video card to another brand on a working Debian 3.0 
system.  The monitor will not be changing.  Is there a published procedure 
for doing this somewhere?

Something like this?

1. backup stuff
2. disable kdm
2. power down and change video card
3. power up
4. as root, run one of:

X -configure
anXious
xf86config
(etc..)

5. as user, run startx
6. tune

What if this get hosed?  I see why test based email clients are a good idea.  
Should I plan on setting up a text email client prior to the change so I can 
ask for help?

Thanks,
