(this is under 1.4.2;  it's easier for me to make bootfloppies)

The patch you provided does seem to detect the 896 as a 64-bit device,
but the problem still remains:

ncr0 at pci0 dev 11 function 0: ncr 53c896 fast40 wide scsi
64bit PCI device

...When I combine your patch with Izumi Tsutsui's NCR_IOMAPPED patch from
kern/6565, it comes closer to working, but still no dice:
