Thanks for the reply.

I'm using whatever is in 2.6.20-1.2952.fc6 fedora kernel (AMD64). I don't know
how that matches up with the normal kernel releases. I tried an
earlier kernel and
compiled the kernel module from pvrusb2-mci-20070428, but that does not change
any of the other modules. It worked about the same and I decided to
try the latest FC6 kernel. Let me know how I can tell what the source
version is.
I can download the fedora source and look at it, if I know where to look.

modinfo gives me the following:
