No, i do not think so. I have applied the NEWTUNE/TS204 bugfix patch
(dst_tuner_fix.patch) + a fix for "FE_GET_FRONTEND returns wrong
frequency for TwinHan DST cards" (dst-getfreq.patch). I might do
someting eles wrong, so here is some information about my Twinhan card
and how I have tested it.


Here is what I get from dmesg:
