Did you get any help with this?

I know it might not help much, but the cz serial cards work just fine. I
debugged a Cyclades-Z 16e on my G3. :-)

syssrc/sys/dec/pci/cy_pci.c is the pci-specific code for the driver, and
syssrc/sys/dev/ic/cy.c is the bus-independent part of the driver.

You might also talk with tsubai, as he was the one who enabled cy
support. :-)
