I don't know about the HD-3000, but the driver for the PVR500 is 
CONFIG_VIDEO_IVTV. In 'make menuconfig' or 'make xconfig', you will find it 
under Device Drivers => Multimedia support => Media PCI Adapters => Conexant 
cx23416/cx23415 MPEG encoder/decoder support. I also turn on the two options in 
that section.
