Looks like you need to update xset to a version with the fix to
make xset not display that message - it should still have worked,
just used the XKB extension after it found XFree86-Misc was missing.

The fix was:

which was included in the xset 1.1.0 release included in X11R7.5.

There's nothing you can add to xorg.conf to fix the bug in xset.

It went into the tree, it just didn't fix the bug you are seeing,
since it only fixed the query path used by 'xset q', not the set
path used by 'xset r'.
