Keyboard handler works
...
You do have you make sure to read from 0x60 to make further interrupts
happen. Also I'm told this might be unreliable because you actually have
to make sure you're draining all the bytes, and this assumes only one
byte

All this does is print a V to the screen, but it means caling asm from
rust works. Remember that if this were in boot.asm, it'd be now-invalid
32 bit code and calling it would cause a page fault.
