You hit an itching spot. Currently the easiest way is to put ofwboot and
the kernel into the boot partition and create a custom kernel with

 config netbsd root on wd0a

in the config file.

The right solution (after Tyler has commited his boot.cfg parsing unification)
would be to allow overriding of the root filesystem in boot.cfg. Also
it should be possible (not right now, but after that commit and a few MD
adjustement) to put "boot wd0a" into boot.cfg and just place boot.cfg and
ofwboot inside the boot partition.

A very similar issue happens on bootable CDs, where firmware always boots from
the :f partition, and we override this in boot.cfg to switch to :a.
