Native NetBSD booloader could do that, with the addition of a bootinfo
field with LBA offset and size for the partition from where the kernel was
loaded.

A multiboot bootloader cannot, because all the information that is passed
is about partition numbers. There is no way of specifying a LBA offset, 
hence the setup where you have a GPT inside raidframe seems impossible
to support.
