Ok, I found some more hints. The nv-tv-out project
(http://sourceforge.net/projects/nv-tv-out/) is primarily for nVidia
cards. But they have code to detect the i845 and lotrs of TV encoders.
Initially, I had some trouble getting the code from cvs to configure and
compile. After I did 'touch test/Makefile.in' and added the FreeBSD
patch
(http://sourceforge.net/tracker/index.php?func=detail&aid=833022&group
_id=33758&atid=409194) I was able to compile it (it still fails, but
that is after it has compiled the src directory), and it gave me a nvtv
binary. 
Running 'nvtv -P' on the machine produces output, it detects the i845,
complains about missing support for CH7009, and decides to list the I2C
device at 2:EC as a Chrontel 7011 (which probably is an error). See 
attached file. Still, this is progress. :-)
