Bootloader: Clear screen, better memcpy
...
Clear screen before jumping to kernel. Memcpy now uses ebx as offset
register, so only one register has to updated every loop

Kernel: Serial now uses random size for some serial ports
...
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
determine its size.

The os itself only supports x86 so this won't matter. x86_64 and i386
use the same bootloader assembly.
