Why drop it? We also don't drop vax just because VAXen are obsolete :)

Are there any details about the changes between the 2 version? I think, it
should be possible to integrate both interface versions into a single port.
Maybe autodetected, maybe minor changes to the interfaces, and in worst cases
maybe a switch in the hypervisor bus stuff depending on Xen version.

But first of all... start with that, what already worked some time. And this
seems to be a real problem. NetBSD/xen seems completely broken somehow. I just
build a kernel from 28-apr-2004 and somewhen in may, when there was some bigger
checkin - always the same problem, Xen/NetBSD eats all the CPU and does
nothing. Tried this with all available Xen binaries and the xen12 package.
Something is really broken here.
