card not detected

[Kris Van Bruwaene <krvbr yahoo co uk>]

I'm receiving dvb-t on Ubuntu Lucid amd64 with Kaffeine. I just wanted to try out gnome-dvb, but it didn't detect my card, a PCI card, manufacturer unknown (could be Siemens or Philips), which identifies itself with lspci as:

00:0b.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)

and in dmesg:
[   14.845348] saa7146: register extension 'Multimedia eXtension Board'.
[   14.873118] Multimedia eXtension Board 0000:00:0b.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[   14.873197] saa7146: found saa7146 @ mem ffffc9000051e000 (revision 1, irq 16) (0x0000,0x0000).
[   19.619632] saa7146: register extension 'hexium HV-PCI6 Orion'.

Any idea how to proceed?
