I guess this "xen-headers" package only includes *.h files
which is not sufficient for building kernel-modules.
Please check if there is some kind of kernel development
package around for your xen0 kernel (like it is for FC5).
If this is not the case, then i guess you need to recompile
and install the xen0 kernel manually in order to setup
the right infrastructure for kernel module compilation.
