Of course, but with information from the bootloader there is no need for
probe and autodetection.

I can understand that a LiveCD is expected to boot in any environment so
there a robust probing is required. But an *installed operating system*
will probably be booted on the same hardware through out it's life.

Then there is the issue with USB input devices. I don't know how this
works exactly but isn't the bios capable of providing support for this.
Can a switch to USB drivers be done later in the boot so that usb driver
loading can be done in parallell?
