Probably not. But anyway... I would like simple combos to be handled
nicely. Like shift+7 (forward slash). And then if you have some weird
keyboard you should be able to generate unicode key based on some easy
way and to handle capslock + shift to make lowercase and uppercase
characters.

We need to uniform keyboard handling in way that USB and AT and bios
keyboards get handled in same path.

Now the next issue is if we have like two usb keyboards. How it should
work in grub's case is that both is listened for input.
