Marc,
Well the steering bits are actually being set, and it does seem to work!  What threw me off (and I apologize for not testing this more) was the fact that with a normal kernel (2.6.20 plus PCI debugging), you get messages like this at bootup:

IRQ for 0000:00:15.0[A] -> PIRQ 02, mask 0800, excl 0000 -> newirq=11 ... failed
PCI: Guessed IRQ 11 for device 0000:00:15.0
natsemi eth0: NatSemi DP8381[56] at 0xfebf2000 (0000:00:15.0), 00:50:f6:22:91:4e, IRQ 11, port TP.

The "failed" messages concerned me.  However, in reality, the devices work, and you can verify that the interrupts are routed properly via /proc/interrupts.
With the same kernel, but patched to know the CS5530 IRQ router, you don't get the "failed" messages.

So since things work, I'm about ready to claim success.  Are the "failed" messages an acceptable artifact of the kernel not knowing the CS5530 router, or something I should be concerned about?

thanks,
Jonathan
