You can use 0.90 or 1.0 metadata. Both leave the partitions underneath looking like it has a simple (non-RAID) filesystem on each disc of a mirror when the EFI or BIOS looks at the drives. I think that's what they need to boot from, so I don't think there's any chance of booting from a /boot/efi which is an lv in a vg on several pvs. Maybe LinuxBIOS?
