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

description: Driver for NXP SAA7164 based TV cards
srcversion: 1F4BCC26D2D3BC0BBCFADB7
alias: pci:v00001131d00007164sv*sd*bc*sc*i*
depends: dvb-core,tveeprom
vermagic: 2.6.31-20-generic SMP mod_unload modversions 586
parm: adapter_nr:DVB adapter numbers (array of short)
parm: waitsecs:int
parm: debug:enable debug messages (int)
parm: card:card type (array of int)
root at sayfair:/home/andre#
So
options saa7164 adapter_nr=170,171
Should do what you want.
