kprobes is on in our current rawhide kernel-xen config.  But systemtap is broken
in other ways (it fails to compile the stap scripts due to a #warning in
<linux/config.h>).  It's apparently fixed in upstream systemtap CVS, so when the
fix propagates to rawhide I'll be able to test if it's actually working.

I got a direct kprobes test case from fche; all works fine on a Xen domU.
