First step, though -- no one has mentioned yet what exactly is broken
-- does anyone know exactly?  Andrew said he brought up a machine and
it then started to lose, but not exactly what was losing. Once we know
what's broken it should be possible to figure out what we want to do
-- it might be ten minutes work (in which case why not) or it might be
very bad in which case perhaps we let it die.

A prime example of something that's broken is the sqrt() (or is fsqrt()?) function, which is used in programs such as ping(8)...

i486> ping mac

Hope this helps, I'm interested in this. I've got an old 486-SX that's running NetBSD-3.1, so I can check stuff out if needed. I'm a newbie, though, so provide precise instructions ;-)
