When udev loads the configuration for the device:

00:0d.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32 (5000ns min, 13750ns max), Cache Line Size 08
        Interrupt: pin A routed to IRQ 19
        Region 0: Memory at ed000000 (32-bit, non-prefetchable) [size=16M]
        Capabilities: [44] Vital Product Data
        Capabilities: [4c] Power Management version 2
                Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-


 this passing to the modulos the wrong configuration while the certainty would have to be
cx88xx card=27 i2c_scan=1
tuner
cx8800
