I have some good news for those of you who have a librebooted macbook 2.1 and ran into the issue of "--MORE--Unknown key 0xff detected"-spam when starting the laptop. That issue might be fixed now. For more details about the problem I refer you to:

I did two changes after which the problem is gone (at least hasn't appeared during the past two days).

- I compiled a recent libreboot and rom (macbook21_svenska_vesafb.rom) from source. It was at commit 7c5fc471cfcdc48086491c87773a3667ae016873 from their git repository at git://git.savannah.nongnu.org/libreboot.git

- I used the cbfstool to use my old grub.cfg in the new rom. In addition I had added the line "terminal_output --append cbmemc" into this grub.cfg. I have no idea what it does, but this was added in one of the commits since last release, which was in may this year.

So hopefully this will get rid of an extremely annoying issue for some of the more adventurous of you.

Happy new year!
