Missing mouse cursor in FC5-x86-64 installation.

[Gordon Gallup]

 Greetings All,
   I executed an apparently successful installation of FC5 on an
e-machine T6420 with an Athlon64 CPU.  The only trouble is that at the
XDM window and later the mouse cursor does not show on the screen.
(It shows OK in a tty text window.)  X-windows knows where it should
be.  I can search blindly for places that icons brighten and carefully
get into menus, etc.

   This may, of course, be an X-windows issue, but any advice from
this group would be appreciated.
