The RH6.1 /etc/X11/xinit/xinitrc runs xmodmap on
the users .Xmodmap file twice, assuming that the
setxkbmap is not being used.

For many people, this behavior is probably
harmless.  But my .Xmodmap uses keysms (not
keycodes) to swap the caps_lock and the right-hand
control keys.  Running xmodmap twice swaps the
keys twice, which is the same as not swapping them
at all!

The relevant lines from xinitrc (lines 40-60) are
below.  The first 'xmodmap $usermodmap' inside the
XKB_IN_USE conditional is probably the intended
one.  I think the second one was just accidentally
left in the file, and should be deleted.

I almost hate to submit this because xinitrc
currently has zarro boogs :-)
