Nope - that didn't do it.
I see the warning during compile:
WARNING: "__video_register_device" [/usr/src/hdpvr-driver/media_build/v4l/hdpvr.ko] undefined!
which I suspect means the v4l2-dev.c is not being compiled. As suggested in the wiki, I set all =m to =n other than the HDPVR, but I suspect that is no longer good advice. Some other CONFIG option has to be set to m/y but it's beyond me to figure out which...

Reboot your PC. This happens when you have a combination of old and
new modules running. Assuming you've done a "make install" in the
tree, you just need to reboot so that the running copies are all the
