For the record, everything is working happily now.  I returned to the 
default settings that didn't work two weeks ago, and now they work.  In 
the kernel config:

device          pcic0   at isa? irq 0 port 0x3e0 iomem 0xd0000
device          pcic1   at isa? irq 0 port 0x3e2 iomem 0xd4000 disable
options         PCIC_RESUME_RESET       # reset pccards after resume
device          card

and everything works with PCI interrupt routing.  I knew it would turn out 
that someone had already solved the problem ;-)

I still don't know why it wasn't working.  Clearly something was 
misconfigured, but I'm not sure what.  I did end up wiping the entire 
source tree and starting over because I couldn't install world at one 
point, so I suspect something was out of sync.
