Sounds like you have the same problem that I have. I have an HD-5000 DVB card that will not initialize even though it is detected by the system. I think the firmware is not loading cause I'm missing the "firmware_class.ko" kernel module. More info in this thread:

Open a terminal window and "su-" as root type (or cut and paste):
modinfo firmware_class
What does it say?? You can also try
modprobe firmware_class
And see what happens. I don't have a fix yet, but if we can get someone's attention we might get both our problems solved
