Its pretty painless. I have a toolchain sitting around in
http://people.freebsd.org/~dfr/ia64-toolchain.tar.gz and a sample
filesystem in ia64-fs.tar.gz.

Ski runs quite well on -current with the one problem that it sets vmin and
vtime for the console pty to 255 instead of zero. If you can work out
which pty its using (just look for bogus vmin values with stty), you can
use something like:

	$ stty min 0 time 0 < /dev/ttypXX

as a workaround.
