Still i have seen such a problem on my laptop (Dell Inspiron 3500).
The pcic works in polled mode and i have finally discovered it works in
interrupt mode with the following config
device          pcic0   at isa? irq 9 port 0x3e0 iomem 0xd4000
However under windows and freebsd 3.3+PAO it worked on IRQ 11
Under 4.0 IRQ 11 appears as used by the Neomagic Sound Card.
It is not used by freebsd on this IRQ since the config is:
device          pcm0 at isa? irq 5 drq 0 flags 0x11
I have even tried to use the visual config screen to put IRQ to 11
(which did not work) and hot reboot to IRQ 9. Then the pcic still did NOT
work. I had to cold reboot to get it to work again.

Similarly the USB controller gets hooked on IRQ 10 (as in windows) and does
NOT work (it was the same on freebsd 3.3). No insertion or removal events are
reported. On another machine i have this works OK. Finally the iicbus
and smbus stuff don't work either. I think they both share IRQ10 and this
causes problem. These are PCI devices and i cannot do anything to change the
IRQ settings.
