Regression: Nebula DigiTV DVB-T (PCI) no longer works

[Stephen Bainbridge <bainbridge.stephen@gmail.com>]

Hi,

My Nebula DigiTV DVB-T (PCI) card no longer works. It's on a
multi-boot Kubuntu system and works fine when I boot into Intrepid
(v2.6.27-11-generic#1 SMP i686), but it does not work with Jaunty
(v2.6.28-11-generic i686). I've also tried a beta of the latest Kubuntu
release Karmic and that also does not work. I've tried both i686 and
x64 variants and its the same.

I did a clean install and when I try to scan for channels using Kaffeine
it gets nothing and displays the following:

fred@cartman:/media$ kaffeine

Any pointers how this may be resolved ?
