disklabel format incompatible with freebsd-4?

Basically the issue with the disk label is that it's bigger. Older
FreeBSD disklabels were organized like this:
[disklabel][unused_space][boot2]
And are in fact compatible with our new larger disklabel with a few minor
changes. HOWEVER, newer FreeBSD disklabels which support UFS and UFS2
booting are organized like this:
[disklabel[much_larger_boot2]
And do not have any free space and are thus not compatible with our new
larger disklabel :-(. That's just the way it is. DragonFly should
recognize and support a FreeBSD disklabel but it won't work the other
way around. I don't recommend mixing partitions anyway.
