Hi everybody,
within the current kernel concept you are forced to compile the dst and dst-ca
modules and delete them afterwards if you enabled DVB_CORE_ATTACH.
With this patch you optimize RAM usage for all bt8xx DVB-S abd DVB-T cards with
the following known exceptions (please correct this list if one or more cards
are missing):
1. Pinnacle PCTV Sat with CI extension
2. TwinHan DST and clones
3. TwinHan DST with CA slot
4. Chaintech DST-1000
5. DNTV Live !
Please acknowledge this only in connection with the bt8xx documentation fix (i.
e. patch 1 / 2).
Written, tested with a Pinnacle PCTV Sat without CI extension and:

P. S.: My past attempts on that patch were based on the assumption that a
Pinnacle PCTV Sat with CI extension can run with the modules combination
dvb-bt8xx plus DST-CA. That assumption was wrong. My apologies for that. But
this patch should be OK now.
