Yes, I'll post the patch to distribution's kexec-tools. ``kexec-tools''
seems a little ambiguous; the users scripts on fedora are contained
in the same package.

I don't know things on other distributions mostly at all; I've read
Ubuntu's scripts really a little bit only. I'd like anyone to post patches
if necessary...

BTW, what's the status of this patch set? I've redesigned this so as to
be done with kernel parameter in order not to depend on platform specific
BIOS table. Due to the redesign, I think now ACK is needed again.
