Hmmm... bttv was installed by my Mandrake 9.1 install
and it's always just worked.  lsmod lists

bttv                   78496   0  [lirc_gpio]
videodev                7872   3  [bttv]
i2c-algo-bit            9064   1  [bttv]
i2c-core               21192   0  [tuner bttv
i2c-algo-bit]
soundcore               6276   0  [snd bttv]

My modules.conf is
 
alias char-major-61 lirc_gpio
probeall usb-interface usb-uhci
above snd-via82xx snd-pcm-oss
alias eth0 3c59x
alias sound-slot-0 snd-via82xx
options bttv card=78 tuner=2 radio=1 gbuffers=4
alias /dev/nvidia*   nvidia

modules.devfs, which is auto-generated when devfs
starts, has a comment that reads

#   Sample configurations that you may want to place
in /etc/modules.conf
#
#alias          sound-slot-0            sb
#alias          /dev/v4l                bttv
#alias          /dev/misc/watchdog      pcwd
#alias          gen-md                  raid0
#alias          /dev/joysticks          joystick
#probeall       scsi_hostadapter        sym53c8xx

I'm not sure what to make of that.
