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.)
