Can you use the wheel with other applications?

If not you have to enable it on your X server.  Probably you've chosen a
simple PS/2 mouse in your X configuration, so the X server is not
looking for any sort of wheel motion.

You need to choose a mouse driver like ImPS/2, and enable ZAxixMapping;
for example from my /etc/X11/XF86Config file:

  Section "InputDevice"
          Identifier      "Configured Mouse"
          Driver          "mouse"
          Option          "CorePointer"
          Option          "Device"                "/dev/psaux"
          Option          "Protocol"              "ImPS/2"
          Option          "ZAxisMapping"          "4 5"
  EndSection

Note this might not be right for your mouse, depending on what kind you
have.


Anyway, unless your wheel works for all other apps _except_ for Emacs,
for more info please post to a group or list that's related to Linux,
Red Hat, or XFree86 in particular: this isn't an Emacs issue.
