kernel-xen in Fedora is part of the distribution, it's maintained by Fedora
(Redhat) developers.
Fedora currently ships kernel-xen-2.6.20, which is a lot newer than the one
xensource is shipping (2.6.18). That means fedora developers have ported the
xen stuff for the newer kernel.. and there seems to be some bugs in it.
And yes, you should be able to use the xensource kernels with the fedora xen
hypervisor.. just pick up the PAE kernels, as fedora hypervisor is PAE.
