The screen's native resolution is 1280x800, but all the specs say is
that it supports "millions of color2", so it could be 24 bpp.

And, what happens if you set this mode using `gop NNN' at the bootloader
prompt?

No change when attempting to boot.


So, it's not a pitch (AKA stride) issue: pitch matches resolution.
And, doesn't look like a 24-bit vs. 32-bit mismatch between bootloader and
kernel...

Looking at that screenshot again however, it still looks very much like what
would happen if there was some mis-agreement between the bootloader and the
kernel.

Is the bootloader the one built along with the kernel, or a very old one?
(the kernel version it was built against should be printed in the banner.)
