The patch-a* patches you added to xenkernel3-nb1 are also in xen-unstable.
(AFAIR I mailed you, Manuel, when I got the Xen-kernel building on
NetBSD.) See changeset 15177 for the proof :-)
In short: When Xen 3.2 is out, no additional patches are necessary
to build the xen-kernel - except patch-aa if you continue to build
a *debug* Xen kernel.
