It's a 53c895/KZPCA, the one that ships with the XP1000.

I can't easily get the dmesg output from the siop driver.  It doesn't 
work well enough for me to get that far.  It doesn't find any disks 
so I end up with this: 

    siop0: scsi bus reset
    WARNING: can't figure what device matches "SCSI 0 12 0 1 100 0 0"
    root device:
    use one of: ti0 fxp0 fxp1 fxp2 fxp3 fd0[a-h] tlp0 fpa0 tlp1 halt
    root device: halt
    syncing disks... done

Here is what the ncr driver says:

    ncr0 at pci0 dev 12 function 0: ncr 53c895 fast40 wide scsi
    ncr0: interrupting at dec 6600 irq 36
    ncr0: minsync=25, maxsync=254, maxoffs=31, 128 dwords burst, large dma fifo
    ncr0: single-ended, open drain IRQ driver, using on-chip SRAM
    ncr0: restart (scsi reset).

The siop info in my previous message was the top of a dmesg printout 
after going through a halt/reboot cycle.  Where does that info get 
saved?  I assume it's a buffer in memory someplace.  Who owns/allocates 
that buffer?  Can I easily make it bigger?  (so I can get more info 
from the previous attempt) 

I'll see if I can hookup a RS232 cable and grab the printout that
