That part I've got working in my next release of osst.c which I'll be  
submitting soon upstream to linux-kernel/linux-scsi.

What I'm trying to also make work is that osst.ko gets auto-loaded at boot,  
just as st.ko does today. If that doesn't happen, a FC3 system won't have osst  
device nodes, which would seriously inconvenience Onstream owners.

Having hwconf be correct in and of itself is a nice-to-have, if it doesn't  
drive anything else.

By vendor and type returned by the device. In terms of hwconf, if "desc:"  
starts with "Onstream SC", "Onstream DI", "Onstream USB", or "Onstream FW",  
then the device needs the osst device driver. Note that "Onstream ADR Series"  
is reported by a second generation drive, which should be driven by st.

Alternatively, if "st" reports the following line to syslog:
Oct 23 08:55:18 fallguy kernel: st: The suggested driver is osst.

Thanks, Willem Riede.
