Thanks - There are questions from time to time on how to test ia64
for those people who do not have hardware.

Let me know how that goes - I haven't used ski in a decade and
have quite forgotten how to set it up.

It seems that there are at least two of you out there - so I'm happy
to take kernel patches that make things better.  Not sure where the
ski patches go - is someone maintaining that?
