After these install procedures, I tried using grub to load the slice.
I tried chainloader'ing it, as well as specifying a kernel
/boot/loader.  The first gave me an Error 13: invalid or unsupported
execution format" and the second an Error 17: unable to mount
partition error.
Does anyone have suggestions for getting Grub to dual-boot a HAMMER
DragonflyBSD?  If this is hopeless, what can I do to place the
absolute minimum amount of code on a bootable non-HAMMER area, and the
dominant part of DBSD in Hammer?
Hopeless.  You'll at least need a /boot UFS partition.  Also you'll 
probably have to modify grub to read DragonFly disklabels (although I 
have a setup here booting with grub, so I don't know how I managed that 
:).  Oh yes, you'd need a disklabel32, not a disklabel64 to have the 
slightest chance of making grub work.

Or try a /boot in ext2, then also grub should be able to read it :D

Alternatively you could try using a chainloader in grub.
