I downloaded the latest 2.6.24 ubuntu kernel, built it and installed it.
Unfortunately, I still get the same errors when I try to "modprobe gspca":
[ 57.028476] gspca: disagrees about version of symbol video_devdata
[ 57.028481] gspca: Unknown symbol video_devdata

I tried getting the latest v4l-dvb hg tree to see if that would help
but it failed to compile:
