IMHO, this is the better for saa7146 boards. bttv is a monolithic driver for all devices using Bt8x8 chipsets, whereas saa7146 and saa7146_vv only hold the core infrastructure that is common for all saa7146 cards. saa7146 does not know anything about a card, but the so-called extension driver (like mxb, hexium_orion or dpc7146) does. It holds the PCI IDs and is responsible for telling the system what card it supports and do any probing if necessary. I don't know where to put the card=xx parameter in that case, because the hexium_orion does not know mxb nor dpc7146. 8-( Since these cards don't have subvendor/subdevice IDs, it's impossible to find out which card is in the system.
