Thanks for all the advice guys. I managed to sort it out by creating the RDB and the partitions with parted and then using the -o flag with losetup to mount the partition with the correct offset as /dev/loop7.
Then it was just a matter of using mkfs.ext4 on the loopback device then mounting that filesystem as /mnt and extracting m68k-base.tgz into it, remembering the p option too! :) However, upon running 'amiboot-5.6 -d -k vmlinuz-3.2.0-4-amiga root=/dev/sda3 fb=false' from a boot without startup-sequence I get a "compressed image is too large! Aborting." error so until i figure out this issue I have no idea if the partitioning voodoo I carried out actually worked yet.
