At this point your best option is to run FreeBSD-4.5 on them.

I have three such machines now running FreeBSD-4.4 and 4.5 and squid and
they've been stellar performers.  FreeBSD can also take at least some
advantage of the optional second processor (one of the squids I set up
and help run is running on two processors).

NetBSD-1.5W just does not run on them with more than one Ultra-160 drive
attached on the U-160 bus, and the problems I saw when trying to make
them work look very much like what you've reported.  The ahc driver
needs to be re-ported from FreeBSD before we can expect these machines
to perform properly with NetBSD again.

I have a couple more of them running NetBSD-1.5W, one as a database and
general administration server, but each has only one Ultra-160 drive
attached, and of course it doesn't attach at 160MB/s, but only 80MB/s.
In this example there is a second drive on the second bus:
