Yeah, don't construe my comments as a recommendation
to use IPMI. I was just pointing how remote reset
typically works with current machines.

And there's no indication this situation will improve
any time soon.

(Graphical) console redirection isn't a good solution for
non-mswindows machines, it's way too fragile. For anything
sane good solutions exist already (serial lines, telnet,
that kind of thing). Not much consumer-class stuff has
support for these things built in though.
