description:
Pull up following revision(s) (requested by rin in ticket #837):

        sys/arch/macppc/stand/ofwboot/Locore.c: revision 1.34
        sys/arch/powerpc/oea/ofw_consinit.c: revision 1.18

When boot up with auto-boot? == true, some systems do not provide stdout
if the normal output is screen.

Open screen explicitly as stdout in this case, both for ofwboot and kernel,
which fixes problems with auto-boot? == true for Mac mini G4:
- messages from ofwboot do not appear
- kernel freeze during early boot stage

Taken from OpenBSD:
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/arch/macppc/macppc/ofw_machdep.c#rev1.3
