Hello Shin'ya

I'm really thankful for all your provided help. I've got now a
successfull build, that i'm going to test ASAP.

However, i would like to know if it's possible to use a newer kernel
(like 2.6.30 or newer) with Xen 4.0 in Dom0 / DomU configuration to take
advantage of the new features in it.

I've tried jeremy's patchset (2.6.3x-stable) and it doesn't compile on IA64.

Anyhow, i'll shortly post details on how to successfully build al xen
vanilla components on Debian IA64.

Have a nice day.
