so both parport and serial is on the same IRQ: #7, but the parport one does not support shared interrupt lines (IRQF_SHARED). You can probably change the mapping in the BIOS (change the serial one to say IRQ#3 or IRQ#4). I suspect you dont have any real parallel port hardware attached? (and probably no serial port hardware either?) So you can safely ignore this.
