I guess this translates to uncommenting #define POLL_MODE and setting
#define MIN_DMA_LEN 0x100000000 (so big that DMA is never tried) 
in arch/vax/vsa/ncr.c?

Hmmm... I replaced all `SEND_IDENTIFY' with `NOOP' in
dev/ic/ncr5380sdr.c. I don't understand why it makes the RZ57 work,
and it probably breaks any other SCSI device... Maybe someone with a
better knowledge of the SCSI protocol and/or the RZ series disks could
comment?
