I might be missing something, but AFAICT VESA mode numbers are only passed
by the user in the "vga=" option.

There's also the `vid_mode' parameter in Linux header, but it's only used by
legacy code, and with the 32-bit boot protocol Linux doesn't read it.

Does 0x0F04 really do something when used in combination with Linux' vesafb?
