Yes, that's it. At this time, the following 4
lines can be added to achieve the switch:

	nooption	GEOM_BSD
	nooption	GEOM_MBR
	options 	GEOM_PART_BSD
	options 	GEOM_PART_MBR

Yes, I saw the commit. Do you know if there's anything
we can check for in case there's no DDR?

I'm thinking of accepting a DDR-less APM scheme only if
we find some indication that it's a Tivo disk. I guess
I like the comfort of checking the DDR and prefer not to
eliminate it unconditionally. This may not be possible
though...
