We were honestly surprised ourselves, but no matter what we did - the furthest we got was 'Welcome to GRUB!' and never any further - I'll have a closer look into the firmware aspect of it - maybe there is an issue that is preventing GRUB from working correctly tho like you already mentioned, Yaboot does work (if installed via the Debian installer) so what exactly is the issue is hard to tell right now. If we find anything useful I'll report back
