Maybe your problem comes from the change happened in the kernel 2.6.20.
You don't use anymore devfs but udev. So, you should write a udev script
like this one :
#v4l devices
#KERNEL="video[0-9]*", NAME="v4l/video%n", SYMLINK="%k"
#KERNEL="vbi[0-9]*", NAME="v4l/vib%n", SYMLINK="%k"
#drivers
DRIVERS=="ivtv", ATTR{name}=="ivtv? encoder MPEG",
KERNELS=="0000:05:01.0", SYMLINK+="pvr_350_1"
DRIVERS=="ivtv", ATTR{name}=="ivtv? encoder PCM audio",
KERNELS=="0000:05:01.0", SYMLINK+="pvr_350_1_audio"
ACTION=="add", SUBSYSTEM=="firmware", ENV{FIRMWARE}=="*",
RUN+="/lib/udev/firmware.sh", OPTIONS="last_rule"
And as hotplug is no more used by udev, I advise you to put your
firmware in /lib/firmware.
On my Gentoo, I'm working like that.
Hope I could have provided you some helps.
