Hi Daniel,
I'm not really qualified to answer your questions, but two things:
- the memtest86+ payload does not boot (or it boots but shows no image, I
don't know. Is it possible to make memtest86+ use the 1680x1050 resolution?).
The libreboot project publishes extra ROMs for memtest, which use text mode instead of vesafb. So I think it's not possible to make it use 1680x1050.
Second, please try to break lines at 72 or 75 characters :)
Regards,
Merlin
