First, you are right, using the new sym driver the card works. But:
1. it doesn't build (2.5.43) as a module, up through -mm3
2. the ncr module works in 2.4, and should work or be remnoved.
Typically we keep old modules, like the something7,8xx (yes, comma
in the module name).
3. Building in makes it load before the ide-scsi module, and changes all
the device name and assignments. I have enough problems going between
2.4 and 2.5, I'm afraid of ising devfs on top of that. If it works.

Most good catch, I saw the ncr52c8xx and missed the module name, don't
know how that got turned on.
So I can run as long as I'm very ccareful what scripts do, and the ncr
module could be fix (probably trivial) or the sym-2 could be made to work
as a module. I can provide the config and anything else if that proves
hard to replicate, I'm in the habbit of building almost everything as a
module, so I hit rather more of these problems than I would like.
Again thanks for the catch, I'm working, the system uses all devices, and
the swap of /dev/sc0<=>/dev/scd1 assignment is acceptable for a
development machine. I'll probably change the scripts to use cdrom1..N and
just make the symlinks in rc.local.
I couldn't get netfilter to build as modules the last time I tried, I have
to look at that Wednesday, when I'm back in the office.
