Sounds good to me. You might want to look at GRUB2's grub_dprintf(),
which has proven invaluable for low-level remote debugging. Basically
you can just tell someone to run "set debug=disk" at runtime to enable
the "disk" class of debug output. Other classes include partition map,
ELF loading, filesystems, etc. It's nothing revolutionary, but it's been
really really useful.
