My recommendation is always to use the latest released version (currently
3.1). I run -current on my workstation, but 3.0/3.1 on all my production
sparc and sparc64 systems.

Double check that NetBSD has a driver for it - it _should_, but just make
sure. BTW, you may be able to get the PROM to boot from a PCI IDE
controller - see 

As I'm sure you're aware, the U5/10 onboard IDE is horrible. You can pickup
a cheap Symbios 875-based SCSI board (you mentioned SCSI for your DLT
drive) and it'll be recognised by the PROM (ie you can boot from it). _Any_
875-based card will work - the support is built into the PROM.

Be warned that there are still a few thread-related bugs in the sparc and
sparc64 ports. They don't bite that often, but be aware of them. In a
file-server type environment with NFS and or Samba/CIFS you probably won't
see them often if at all though.
