The problem with guesses is that they are guesses and often wrong. Consider a simple case. If I don't have a sound driver configured on my laptop, IRQ 5 could appear to be free. However, IRQ 5 rarely works for pccard card interrupts in modern laptops. PNPBIOS would help that, but w/o PNPBIOS the kernel could easily be fooled. This is a common case if my helping people with their pccard.conf is any example. If was easy, we'd be doing it.
