Just checked (it's raining out) and:

root at sayfair:/home/andre# modinfo saa7164
filename:       /lib/modules/2.6.31-20-generic/kernel/drivers/media/video/saa7164/saa7164.ko

parm:           debug:enable debug messages (int)
parm:           card:card type (array of int)

So 

options saa7164 adapter_nr=170,171

Should do what you want.
