To followup on me, I saw that there is:

- nc53c8xx.c driver
evolution of the FreeBSD driver, which I already use for
a 875 chip. This is developped and works really good, also
for 810 chips. It has all the standard SCSI features (parity,
retrying, scatter/gather, ultra-wide, etc)

- 53c7,8xxx.c driver
old driver, which looks no longer supported, does not really support
the 710 chip, does not support parity, retrying, etc. Works OK with
a 810 chip, except it can completely fail with a single bus error.
Looks to support the PCI chips only, and only on a little-endian
plateform

- ncr53c7xx.c driver
this one looks to be the 53c7,8xxx.c modified to work with a big
endian plateform (Amiga). It looks like it has the same reliability
problems as 53c7,8xxx.c, but it probably supports the 710 chip.
