I don't think so.  I've found one bug so far (I'd never tried looking at
what my I^2C code did before).  I'll see if fixing that helps.

No.  The problem is that NetBSD assumes that the DHCP reply it gets will
contain everything it needs to know, including both its IP address and the
location of its root filesystem.

Yes.

When someone (possibly me) writes it.  I haven't got a data sheet for the
relevant chip yet and there's no code currently in NetBSD that supports
it, so it's not likely to be soon unless someone else does it.

No.  The podule list is common across the two arcitectures.  One day the
rest of the podulebus code will be too.

It should, ignoring a couple of small hacks in my sources (which
shouldn't matter).
