I did some big reading on this and got some stuff working on the 126.96.36.199 kernel went and got the newest xawtv and it is built to work with v4l2 I also built camorama but i had to do this to get it to work
I know I only have a pixart cam and I already have it working in slackware sorry I have been trouble shooting hardware on linux mint6 and not to happy with it . but what it does have in common is instead of using the old pac207 when I did alien bobs gspca build. I did this from source and wanted to use the new pac207 and the new gspca_main and make it work got everything to work with the cam except gyachi.
Again I know they are different cams but really we are both trying to get the new kernel v4l2 to run on the new kernel modules. and this has to do with the gpl licence and going to v4l2 and running it in users space to keep things running through libraries instead of getting a license for every device or programs. hang in there
