There is an rx2620 in our lab, which is currently being used
for other development work. How close is that to the machine you have?
I could probably steal some cycles on it if need be.
If so, is there any chance that you could send me your dom0 kernel
config, just so that we are on the same page.

That is quite odd. I take it that you built kexec-tools by
patching kexec-tools-testing 20061214 as outlined in the BUILD
document. I'm pretty sure I tested this with --append "X -- Y", but
I will recheck this.

Does phys_efi work on linux (w/o xen) for you? I sent patches
to ia64-linux recently, I can send them your way if you like.
I ask because I am intrigued to know if phys_efi (as currently
implemented) works on your platform at all.

Perhaps. I'll test it out. But its much more likely to be bugs in my code :-(
Thanks a lot for testing this out. I do really appreciate it.
