i glanced at an old email thread on the topic the other day, and
it sounded like there was also some thought that the emphasis
should be on tools, like kgdb, which can be more general purpose,
and more widely used and maintained.  to which i'd say, the more
the merrier -- i'd love to use kgdb regularly, but it requires a
second machine, and it ties up scarce serial ports.  so OFW is a
win, for my current uses.

mitch -- i think i saw something that implied OFW could do symbolic
kernel debug -- true?  is there a howto, or other doc somewhere?
