Bootloader: Implement VESA video mode query and pass it to kernel
...
Kernel now gets framebuffer from bootloader. Framebuffer dimensions
and bpp are hardcoded in bootloader, but will probably be read from
config file at some point.

If the serial port doesn't repond with a size, just use a random
one. There is no reason to ditch the whole output if you cannot
