Mouse upgrade on RH7.3

["Brian McGrew" <Brian doubledimension com>]

Kernel 2.4.20
Original Mouse: Dell 2-Button PS/2 Mechanical (No Scroll)
New Mouse: Dell 2-Button USB Optical w/Scroll

Any idea how to make this new mouse work?  Someone at work told me to
replace "PS/2" with "IMPS/2" in /etc/X11/XF86Confg-4 but that doesn't
work; when I do that, the mouse looses it's mind and just jumps around.

Any help is appreciated!
