I'm using essentially the same setup as you (Gentoo 2.6.12 kernel) and
still haven't managed to get CC to work AT ALL on my PVR-350, so hearing
that it's possible is heartening.
Are you using the PVR-350 decoder in MythTV to watch things, or are you
using the built-in (xv?) drivers?

I have a small problem with my pvr-350 and the closed captioning support
using ivtv 0.3.7a drivers and mythtv 0.18.1. When I watch a recorded
tv show
and use the 30 second skip ahead the closed caption stops working. The
captions seem to turn off and not turn back on from what it looks like
in my
dmesg.
I have a small scrip that starts on boot that enables all the closed
caption
support and fixes a few of the ghosting effects.
/usr/local/bin/ivtvctl -l 2 -x 1 -w wss,cc -b wss,cc
--set-codec-params=dnr_mode=0,dnr_temporal=0,dnr_spatial=0
I would love to get the closed captioning support to work after
skipping ahead.
so here is the important parts of the dmesg...
