From my notes on Slackware 11.0(?) thru 12.0,
1) I know that Slackware and Red Hat are configured somewhat
2) I cannot (and my notes do not say) what my mouse was at
but here are the changes I made to get my mouse to work.
line 282 I commented out
added line 283 Option "Protocol" "IMPS/2"
added line 289 Option "ZAXISMAPPING" "4 5"
note: this line may be:
289 Option "ZAxisMapping" "4 5"
I think that line 283 set the mouse as PS/2 so that should
give you an idea of where to look in xorg.conf.
depending on the number of features your mouse has, as I
recall, the numbers can be "4 5 6 7 8" etc.
Google ZAxis Mapping for a lot more info.
