Boot grml/grml-small from usb-stick/firewire-device

"Starting with grml-small 0.1 we officially support booting from usb-stick. First of all make sure your system supports booting via usb/firewire. Some hardware claims to be able to boot via usb/firewire but does not really support it the way it should work."
