Undetected TV cards in SuSe 8.2

Hi all, We just installed SuSe 8.2 on a new PC with two TV tuner cards, both cards are Hauppauge WinTV GO PCI with BT878 chip. Yast2 does not detect any of them, and even after adding them manually in Yast2, TV applications like xawtv do not work (they complain: cannot open /dev/video0, no such device). I also tried doing manual modprobe of bttv and tuner modules with varying values for card type, and it says "No such device". Well, I have never seen this problem before with bt878 chips. Does this problem has anything to do with the new ACPI thingy ? (I did normal installation of SuSe 8.2, which warned that some PCI cards might not be detected...) any help will be appreciated. Best regards, Lokesh Setia.
