I have:

/lib/firmware/v4l-cx23885-avcore-01.fw
/lib/firmware/v4l-cx23885-enc.fw

One site I googled suggests that they should be
in  /lib/firmware/your-kernel-version.  I would think it depends on
where the init looks.  For Fedora 10, since there is no
'/lib/firmware/your-kernel-version' directory it wouldn't be necessary.

I will try that next but first I thought I would straighten out any
problems in dmesg.
