mental note: don't move to a territory Shaw provides cable...

as for your issue, you shouldn't have to unload the firewire modules,
unplugging the cable box from the firewire cable should be enough to
reset it. As for the node change, from what I understand its something
the 6412 determines, so it may not be possible to do anything about.
Your best bet may be to minimize the possibility of the 6412 from
turning off so you don't have this problem under normal conditions.
