GRUB can load any ELF file, but how can it determine what parameters to
pass to it when booting? I know that NetBSD ELF and FreeBSD ELF kernels
expect to find very different data on the stack.
What about COFF, it is not supported directly (i.e. without a Multiboot
header).

I don't quite understand what you are asking here. Actually, if you put a
multiboot header in the file, GRUB will be able to load it, even if uses
COFF or another unsupported format.
If you are trying to boot a kernel that doesn't have a multiboot header,
i.e. Solaris, GRUB will not do it.
