ok, integrated so far, detection and initialisation works, it printks
out some carrier and other messages.

ill take care of the thread without breaking other drivers using the
msp3400.ko.

anyway the msp3400 chip of this card shouldnt be used for dvb audio,
cause the sound output in that way is heavily harmonic distorted and the
proposed "volume setting for dvb with onboard analog mogule" does NOT
work here anyway, at least not with vdr... so we should drop dvb usage
for it. spdif soundcards are cheap nowadays.
