Thanks, John.  I wasn't sure about this port.  I first tried to download
it as a package and started X with the driver "via" (according to the
documentation), but X did not find it.  I then got rid of the package as
well as the old via driver and installed xf86-video-openchrome as a
port.  It still did not work.  However, studying the new error message,
I decided to correct the driver to "openchrome", which DID work.

I must have come across some stale documentation.  At any rate, I can
now start X, and it responds to the Gamma line.  To some extent it also
works with xvidtune.  Screen size and placement is not perfect, but I
hope this can be improved when I have studied the "caveats" mentioned at
the openchrome site.  Things look promising now.
