FWIW, a standard 4-stable system boots fine with the boot
blocks (and loader) from RELENG_6. I'm running such a
mixed system: /boot/* and boot blocks from RELENG_6, and
everything else from RELENG_4.

I think the most visible changes in the boot blocks was
UFS2 support and the removal of nextboot(8) support.
