I have two additional datapoints:

1. The card works properly (ie. with interrupts) in a Apple Network
Server 700 with the same kernel I built for the G3/G4s. 

2. In both the G3 and the G4, the card is in a long PCI slot (64
bit?). There are not regular PCI slots on the G3/G4 motherboards.  In
the ANS700 it's in a regular PCI slot.

Should the driver be aware of 32/64 bit PCI slots? Do they need to be
initialized or handled differently?

Here is the boot log on a ANS 700:
