DGA with XFree 4.3 and Voodoo3?

[Jon Niehof <jon_niehof@xxxxxxxxx>]

So far I haven't been able to get DGA working with any
version of X 4.x so I figured now was as good a time
as any to ask...

When I use any program that uses DGA, my screen goes
black (but not into powersave) and nothing displays.
All other functions of the program work (e.g. sound,
control, etc.)

I'm at a complete loss here and have been unable to
find anyone else with this problem.

XF86 4.3.0, installed from binary tarballs on
xfree86.org
Voodoo3 2000 AGP card

(excessive information dump follows)

Output from "dga" program (timestamped march of 2003,
unlike most of the rest of my X4.3 files--this may be
an old version, but manpage says 4.3):
