I think that a new cheat code 'noprogressbar' could be useful on some systems.
Knoppix knows how many CPUs are there when it is running. Therefore another approach is to be more generous with the sleep when the CPU is one ( at the expense of a little jerky screen update ). When I put a sleep of 5 second, the booting is very fast. A new cheat code adds complexity. Should be avoided unless absolutely necessary.
