I had configured the server for S3 chipset (which is what is used by the Diamond cards) but that didn't work with my card. I didn't even attempt to configure a simple SVGA server, because I wanted higher resolution and lots of colors. So, I downloaded XF86_S3V from Xfree86 web site and did the following to set it up:
ln -s /usr/X11R6/bin/XF86_S3V X
By the way, at this time (March '97) the XF86_S3V server has a limit of how many colors it can display - it only works with 16bpp. There is a beta version that supports 24bpp, but I haven't tried that one yet.
I downloaded the sources for AfterStep-1.0pre02, compiled them, then did did make install and I was up and running. Since then I have fiddled a little with the ".steprc" file to customise my desktop.
Here is what it looks like so far:
