Hi Francis, I am vita_cell, 2 days ago I flashed the latest Libreboot version, in macbook 2,1. Works fine and solves some problems.

Macbook 2,1 (and probably 1,1)(I have 1,1 and if you need, I can test it) has a sound distortion of the left channel (headphones and built-in speakers) in GNU+Linux (it isn't the problem of Libreboot), but this fix it:

I have a t400 8mb with 1440x900 screen (without ATI GPU). After flash it (with  20150518) was not able to boot, I could see only changing fullscreen colors every 3-6 seconds, could fix it with kernel parameter, after that GNU+Linux boots (no grub screen, only blinking colors). The screen works fine with 80-100% of brightness, but below 80% the left side of screen become more darker that right side of screen, Lower the brightness, darker is the left side. After flash it with "libreboot_r20150518fix-776-g7ce97e5_grub_t400_8mb" which improves a bit the dark left side, I was able to boot into GNU+Linux without parameter, so ok, but, now I can hear coil whine if brightness below 100% (absolutely no coil whine at 100%). Lower is the brightness, quieter is the coil while and darker is the left side of the screen.
