Mihai,
I got some success. I did this,
# cd /usr/src (for example)
# git clone git://linuxtv.org/media_build.git
# emerge dev-util/patchutils
# emerge Proc-ProcessTable
# cd media_build
# ./build
# make install
Which will install the latest driver on your running kernel (just in case
make sure /usr/src/linux points to your running kernel sources). Then
reboot.
You should now see that (among other) modules have loaded:
# lsmod
<snip>
em28xx 93528 1 em28xx_dvb
v4l2_common 5254 1 em28xx
videobuf_vmalloc 4167 1 em28xx
videobuf_core 15151 2 em28xx,videobuf_vmalloc
Then try w_scan and dvbscan etc. I got mythtv to scan too now. There were
some warnings and timeouts and I'm not sure if this is normal or not.
You can also do a dmesg -c while scanning to monitor the changes en the
kernel log.

/Fredrik
In my case I have:

yet, w_scan founds nothing.
I was able to scan using the "media_build" install method described
above but when trying to watch a free channel the image and sound was
stuttering severly. I have tried both MythTV and mplayer with similar
results.
I created the channel list for mplayer with:
lintv ~ # dvbscan -x0 -fc /usr/share/dvb/dvb-c/no-Oslo-Get -o zap >
.mplayer/channels.conf
And, for example, I get this output from mplayer plus a very (blocky)
stuttering image and sound:
lin-tv ~ # mplayer dvb://1@"TV8 Oslo" -ao jack
MPlayer SVN-r33094-4.5.3 (C) 2000-2011 MPlayer Team
mplayer: could not connect to socket
