The kernel command tells GRUB to use the normal executable magic. It expects
an ELF image and depending on the OS chooses a strategy to run it. Because
/boot/loader and /kernel have the same type, this works fine.
Chainloading does load a single 512 byte sector and jumps to the start, which
of course is the ELF cookie and doesn't work therefore.
I thought you already read the GRUB docu, which descripted how to load
FreeBSD using kernel :) Otherwise I would have mentioned it directly.

Have fun :)
