Duffy: Improving the Fedora boot experience

There is! The general problem here is that BIOSes aren't terribly reliable in their handling of keyboard buffers - there are system firmwares that routinely leave the keyboard buffer full of junk, even when no keys have been pressed at all. So the first thing we do is clear the buffer and reset all the status flags, then check them again. That brings us to another issue - some firmwares won't start giving you new keypresses (or set the flag that a key has been pressed) once the flag is cleared unless you release the key and press it again.

So in effect, this is a BIOS limitation.
