spurious IRQ complaints

[David Ford]

PCI: No IRQ known for interrupt pin A of device 01:00.0. Please try
using pci=biosirq.

01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 RF
(prog-if 00 [VGA])
        Subsystem: ATI Technologies Inc: Unknown device 0008
        Flags: bus master, stepping, 66Mhz, medium devsel, latency 64
        Memory at e4000000 (32-bit, prefetchable) [size=64M]
        I/O ports at d000 [size=256]
        Memory at e9000000 (32-bit, non-prefetchable) [size=16K]

Does it really need one?
