Sorry, you're right, I really should have added that info. The ipc runs
the complete snapshot-release from ftp.netbsd.org, so it's pretty close
to current.

I'm going to decapitate the rest of my suns in the coming days, and 
hope to be able to give data on ELC, IPC, SLC. (yes, I have a few too
many of them right now ;) 

I'll also try to get a newer (current) and older (1.2) kernel on the
machine, to see what difference it makes. And try the trick with the
DTR, too... cuz right now, I definetly can't login on the tty's (Both!)
of the IPC.

Happy hacking, Paul.
