Aren't deadlines wonderful!?  :)

Takashi, changing the "bypassing BIOS" reference in the availability
spec to "bypassing system firmware" would be a reasonable clarification
for the 3.1 spec.

Nice writeup Khalid.  Go ahead and check in the use case in the "Use
Cases" folder at
http://groups.osdl.org/apps/org/workgroup/cgl_tech_board/documents.php

Khalid, in the scenarios section of the use case, would it be reasonable
to include the use of kexec as the front end to a memory dumper as well?
This would not specifically apply to the fast reboot requirement, but
would demonstrate that the kexec implementation has uses outside of the
linux booting linux scenarios.

There is a whitepaper (a little dated) on kexec that could also be used
as a reference.  See
