I installed RH 6.1 on a computer with a Microsoft
Intellimouse PS/2, so naturally I selected that as the mouse
type when prompted. The mouse worked fine during the
install, but didn't work in X when the system booted. I got
the mouse working by changing the line
in /etc/X11/XF86Config. In addition, I suggest that the
installer should add the line
ZAxisMapping 4 5
to the Pointer section of XF86Config for wheel mice, since
that line alone is enough to make the wheel work in all GTK
Similar Problem: Microsoft IntelliMouse 1.1A PS/2 was dectected by the
installer as a Generic 3 button. Changed this to MS IntelliMouse and
installation went fine, however, once completed and booting into
gnome, the mouse pointer jumped to the top right corner of the screen
and couldn't be moved. Running mouseconfig and selecting Microsoft
IntelliMouse (PS/2) [*] Emulate 3 Buttons updated the XFree86 config
file and the next time gnome started the mouse functioned as expected.

The installer sets the X mouse protocol to PS/2 for an
MS intellimouse. It should set it to IMPS/2 otherwise
X doesnt work (mouse jumps wildly)

During the Mouse Configuration step, I configured my mouse
as a Microsoft Intellimouse (PS/2). When the system was
first brought up into run level 5, there was no mouse point.
I had to drop the system into run level 3, edit the
/etc/X11/XF86Config file and change the protocol from "PS/2"
to "imps/2". Then the mouse worked.

The installer also needs to set the mouse protocol correctly for other mouse
types, for example "MouseManPlusPS/2" for some Logitech mice. Mouseconfig can
set this correctly, and since the installer asks for your specific mouse type it
should be fairly simple to make it set the protocol correctly in XF86Config.
On a related note, it would be very nice if the installer could add the line:
ZAxisMapping 4 5
if you select a mouse that has a wheel.
This is fixed in the latest installer code. Try grabbing the latest RawHide.
