If GRUB no longer works correctly on these systems due to the move to
the generic EFI loader, and we can straight-forwardly identify them
using SMBIOS metadata, I don't anticipate any objections from the GRUB
maintainers.
Cool, that sounds great!
If you can get me the output of 'dmidecode' from preferably more than
one variant of such a system, I can hack up a GRUB patch that
implements the SMBIOS matching and the opt-out.
Sure, below is output from the board I have available. I'll ask the
community members who reported the issues to get me output from their
systems.
