I would like to put in a me-too here.  I've been using hw.pci.mcfg=0
since it was introduced but I still don't know where exactly the problem
is, or how to pinpoint it (bad bios/bad hardware/bad phase of the
moon/etc).  The bleeding versions of other OS'es seem to work out of the
box, though that doesn't mean much - I'm not sure what they do inside.
