Nope, sVr3.2u (sVr3.2 version 2.1) is the first one that supports VGA.
I tried vanilla 3.1 and 3.2 and the do not work. 3.2u does.

I tried 3.1 on an Everex 386/25 with Adaptec ESDI controller and it
worked just fine. Most (if not all) ESDI controllers look just like
ST-506 controllers to the AT-bus. The system doesn't know the difference.
But AT&T Unix may be a bit fussy about what controller you use.
Western Digital and Adaptec should be safe.
You didn't say what controller you use (or what VGA adapter). This however
is the critical information.
