Serving 4.0 from 3.5 certainly doesn't work out of the box, but it looks
like you've discovered the right stuff to make it work.  The SunView
problem sounds like maybe some /dev files are missing -- try using trace
from an rlogin to the 4.0 machine to see what system calls the processes
forked by sunview are making.  A few attempts to get the right pid with
"trace -p" will eventually get the right pid.  Start by doing "trace
sunview" on the 4.0, and if it gets to the first fork, start using the
rlogin method.
