So I am out of luck with this card, it seems... Also, I got one more
card, 'pciconf -lv' tells following about:

none0 at pci0:1:0:0:
class=0x048000 card=0x000013c2 chip=0x71461131 rev=0x01 hdr=0x00
 vendor = 'Animation Technologies Inc'
 device = 'PCIVEN_1131&DEV_7130&SUBSYS_D1091461&REV_013&61AAA01&0&60 (saa7146)'
 class  = multimedia

I found older thread on hackers mailing list in 2006 where someone
mentioned writing driver for saa7146 based cards, but nothing
materialized, so using this one under FreeBSD is not possible either...
so I need something USB based for DVB-S too... OK.
