In addition to other folks' suggestions, have you tried xorgcfg (from a
console log in), xorgconfig (interactive), or, especially, xorgsetup
(automagic)? They're found in /usr/X11R6/bin.

I particularly like xorgsetup, which appears to go have a look at things
and makes a usable /etc/X11/xorg.conf file for you (that you can then
fiddle with). It makes a back up of your existing xorg.conf file, by the
way, so it may be worth a shot to see what X thinks things ought to look
like. You have to be logged in as root and not have X running for any of
these.

The only thing I ever have to do with the xorg.conf file generated by
xorgsetup is add

Option "Emulate3Buttons" "false"
Option "ZAxisMapping" "4 5"

so a microjunk wheel mouse will work.
