Thanks Chris,

I'm helping Cherry, getting this driver compiled. She's using a 2.6.31
kernel (the 10.1.3 build I think) which doesn't have the gspca_cpia1

I looked into back-porting the driver to 2.6.31, there's only a handful
of compile errors but it still might be more work than it's worth.

I did a quick trial with the v4l1 cpia driver and it works with
gstreamer, so it's just a matter of getting cheese to detect it. My
initial investigation leads me to believe that cheese uses HAL to detect
v4l capable devices and the QX3 isn't showing up as v4l capable, so I'll
look into this a bit more.

Any other ideas are welcome :)
