Will do as you instruct.  It'll probably be the weekend before I can get the
shadow systems running for our experiments.  I was running 2.6.22-rc3 at
one point and saw the problem, so we'll probably get something interesting
from the sysrq.

Thanks for the precise insturctions; that's about the right level of detail
for my inexperience doing this sort of thing.  :)

Cheers,
