My system is very similar (except that I get irq 9 for the pcic
controller at the end). As I understand it what is happening is that
the PCI based cardbus controller is being hooked up to irq 11 and
not used there, it is used in 82C146 compatability at irq 9. The net
result is a wasted irq.
I suspect that there is no way round this unless/until the 1131 is
supported directly. I would be delighted to hear otherwise as I have a
severe shortage of irq's on my box and I would love to get irq 11 back.
