John, There is a project called gphoto, the mission of which is to provide support for digital still cameras. Assuming that this camera will take still photos, I would suggest that you go to the webpage gphoto.org and start looking around. I suspect that there would be some general interest about the results of your "guesswork," pparticularly in view of the fact that you have made it work.
If the camera also can (or only can) operate as a "webcam," then essentially you want to look at support for it under video4linux, which would probably involve work on a kernel module. At this time, gphoto envisions the construction of "userspace" software to access an external device (for example uses libusb to connect to USB cameras and not a kernel supporting a particular camera). Also, as I understand things, libgphoto essentially does not support "webcam" hardware, only still cameras. Hope this helps. Also while we are on the topic of camera support: Is there anyone on this mailing list who is running libusb and can send me the output file of "gphoto2 --debug --summary 2>debuglog" for a Jenoptik JD C350? According to reports, this is yet another camera using the SQ905 chip (I am working on the driver for these cameras). The sq905 driver recognizes the Jenoptik JD C350 but chokes when asked to download pictures. What little I have seen of the error messages might indicate that the config info which the camera downloads contains something previously unknown. But I don't have one, so I can't test it.
