Sort of.  To do a new board port in 2.4.9 (in linuxppc_2_4_devel), you
only need to edit arch/ppc/kernel/Makefile, arch/ppc/boot/Makefile and
possibly include/asm-ppc/serial.h.  And arch/ppc/config.in too, of course.
No more new _MACH_xxx's, there's now ppc_md.setup_io_mappings (or so),
to do what used to be done in MMU_init and case'ing of the _MACH.

2_4_devel, http://penguinppc.org/dev/kernel.shtml

Nope.  Follow the examples.

If you submit them.  Here, linuxppc-dev and linuxppc-commit at source.mvista.com
are all good places to try.  The -dev list more so.
