The code has bitrotted a bit. I've been through a distracting year and
haven't really been able to focus on getting things together for a
while now. There's a chance things might change in 2008 :-)

I intend to start from a different point next. HP Ski has been release
as open source [1]. I've got a mostly compiling port to NetBSD, which
I'll clean up and commit at some point. I think I'll focus on user
mode support, ie; getting NetBSD/ia64 binaries to compile and run on
other ports via ski ( a bit like qemu usermode [2] ).

Happy Christmas!
