IRQ 11 is the most UNcommonly used IRQ in legacy systems.
If you look at the IRQ list, you'll see what each one has, and most of them are standard, and have been for a long while, keyboard, system clock, IDE devices etc. If the com ports are active in BIOS during the XP setup, then those are taken too, thus 11 is where all other PnP devices end up.
