Whenever you have a hardware resource conflict, it will more likely be an IRQ conflict rather than an i/o conflict because:

the BIOS sometimes has more of a problem controlling IRQs
there are a lot more I/O addresses than IRQs.
I/O addresses cannot conflict
software tends to mess up IRQs
software tends to correct I/O conflicts
