Ah ha, now I understand your problem!  Python's packaging system is
involved here too.  All the non-top level entry point modules are
supposed to live under the `Mailman' package.  In order to be able to
import from the Mailman package, you must have it's parent directory
on sys.path.  Thus /home/mailman is on sys.path, and you can then
import Mailman.mm_cfg (or "from Mailman import mm_cfg").  You've gotta
specify the `Mailman' package some place though.

You'll notice that 2.0's withlist says

    from Mailman.MailList import MailList

this imports the MailList class from the MailList module inside the
Mailman package.

Hope that helps,
