I've no plans for this yet, but it'd make my pkgsrc bulk-builder life
easier to have 4.x Xen kernels for amd64 and x86_PAE :)

The problem is that both amd64 and i386PAE supoort heavily rely on
x86/x86/pmap.c, which isn't there in 4.x. I don't think switching native
i386 and amd64 to it is desireable in the branch. So, if I ever do it,
I may just do it in some private CVS branch ...
