GRUB already implements its own read-only filesystem drivers for a variety of
filesystems. It sounds like your "readfs" would be duplicating this work.

I suppose it would also be nice not to need dom0 access to modify a domU's
GRUB2 is conveniently very modular. You implement a block driver (Open
Firmware and BIOS drivers are already implemented), and then the filesystem
drivers "just work." You would want to write a small "blkfront" driver and
see exactly how little code you can get away with.
I am a GRUB2 developer and would be happy to help if you have questions.
