David, here is an explanation of what I did to get my usb mouse working. I
have taken it from a previous post so it may not be complete in terms of the
context. As per usual, what you have to do is obscure and involves multiple
point of change and esoteric knowledge. Let me know if this helps...
I discovered through some digging that the 2.4.2 kernel will
not use /dev/mouse anymore, but now uses /dev/input/mice This is better
because it allows usage of both adb and usb mice from the same place
("mieces to pieces" <- obligatory obscure cartoon quote).
This I found also at

Mouse changes:
Benjamin's current kernels are preconfigured to be mostly compatible, just
/dev/adbmouse will be nonfunctional by default. All ADB mice and mouse-like
devices end up as /dev/input/mouseX now and will be mixed onto
/dev/input/mice. If you update your dev package to dev-2.7.18-3b.ppc.rpm or
better, all you have to do is to configure gpm, XFree86 and MOL to use
/dev/mouse with protocol IMPS/2. Xpmac with USB mouse support (eg. rev10) is
able to autodetect this and works like before.
All mouse events end up on /dev/mouse with a common protocol (IMPS/2),
including a new artificial mouse button emulation device. This emulation
device lets you use mouse button emulation (see below) even with USB mice
now :-).

Here's another fun one about using the mouse:

http://www.imaclinux.net/php/imaclinux_faq.php3?single=159

After that you have to point GPM (the textmode mouse cut&paste tool) and
XFree to this device to use it - GPM should be called like:
gpm -t ps2 -m /dev/input/mice
And in X:
Section "Pointer"
Protocol "ImPS/2"
Device "/dev/input/mice"
ZAxisMapping 4 5
EndSection
When you do all of the above, you can use your USB mouse and keyboard

After discovering this, I had to edit /etc/rc.d/init.d/gpm to make the call
given above. Oops, but wait, gpm uses MOUSECONFIG variable which gets its
contents from the /etc/sysconfig/mouse file. Whose contents I had to change
to ps2 instead of Busmouse (yes ps2 instead of ImPS/2- the information for
which I found on some other obscure site that I cannot remember).
The XF86Config file changes worked too. OK, the mouse is working in the
console and in X!
