Perhaps this is applicable...

>From the nvi FAQ:

Q: When I use vi on a Sun console (terminal type sun-34) the screen
   is occasionally trashed, usually when exiting vi!
A: The Sun console can't handle the 'al' capability of the termcap
   entry (the il1 capability of terminfo entries).  If you delete that
   entry from your terminfo/termcap information everything should work
   correctly.
