That puts a different light on it. I have two other PCI cards and a usb 
tuner. It might be easier to go for the USB version and patch my kernel. 
Here is a link to the patch in case anyone finds it useful:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0db3fa2741ad8371c21b3a6785416a4afc0cc1d4

It's a very trivial change.

Ian.
