Interrupts don't get accounted right. Instead of adding them to irq14/irq15
they always seem to be added to irq0.
Here is a sample output of systat (I have "options HZ=1000" in my kernel
config, so 1000 should be normal)

During probe I also noticed this message:
ata-pci0: <Acer Aladdin IV/V IDE controller> rev 0xc1 int a irq 0 on pci0.15.0
^^^^^
ata0 at 0x01f0 irq 14 on ata-pci0
On another machine with VIA chipset I don't see any "int a irq X", but the
interrupts get still accounted for irq0 instead of irq14
This isn't a big deal for me, PCMCIA interrupts do have the same problem.
