I use XP SP3.  I can't reproduce this problem.

The problem going away when you remove (and hence prevent from loading) the
dynamically loaded swrast_dri.so *really* makes this look like a remap problem.

There is some work upstream to remove this rather pointless fork/exec of
xkbcomp and replace it with libxkbcommon, but that now seems unlikely to
appear in X server 1.10.
