    **  Giovanni's fixes to dpeth:
    **  Date: Sat, 03 Sep 2005 11:05:22 +0200
    **  Subject: Minix 3.0.8
    **
    **  Revision 1.3  2005/08/03 11:53:34  jnherder
    **  Miscellaneous cleanups.
    **
    **  Revision 1.2  2005/08/02 15:30:35  jnherder
    **  Various updates to support dynamically starting drivers.
    **  Output during initialization should be suppressed. Unless an error occurs.
    **  Note that main() can now be main(int argc, char **argv) and arguments can
    **  be passed when bringing up the driver.
