[I'm not sure this belongs to freebsd-hardware or to the XFree86
lists/groups]
I have the "video VRAM" (series 3400) variant. I might be the same,
I'm kind of lost into Diamond's changing model names. It has 4Mb too
(all of Diamond origin)

It works fine for me in all modes including those using 4Mb.

That may be an issue, you really should get the 3.1.2E server (latest
beta available last time I checked) from any XFree86 archive.
Also, the S3 server has a "slow_vram" option you might want to try.
Maybe your add-on memory has marginal timings which require driving it
in a more conservative mode.

My only experience is that I returned the only such card I had bought
a few months ago and changed it for a Diamond Stealth, being unable to
run XFree86 on it. The situation might have changed since then.
Good luck,
