dpkg-buildpackage takes care of that.

Yes, it's probably the best for the pfinet changes you want.  I've been
working on X however and need the mouse and kbd translators that aren't
in CVS yet.  IIRC, the debian directory is in CVS and you can build a
CVS tree the same way.  Also, see [1].

I've been cross-compiling gnumach, but building everything else natively.
IIRC, the com stuff is in gnumach CVS.  You should be able to just update
and then cross-compile the usual way.

Don't know.  If not, there were some messages on debian-hurd a few weeks
ago about testing tun0 (right after MB posted about the tunnel changes).
You may be able to adapt that testing to send AT commands to the modem.

HTH,

[1] If you want to build hurd with debugging symbols, which is probably
a good thing for what you're doing, here's a patch-style diff for the
debian/rules file:
