Sounds to me like the common STV0299B/SL1935 or the older STV0299/SL1925 
combination -- but that's pure guessing. Both should work with the 
existing stv0299 driver, maybe some tweaks are necessairy due to 
different crystal frequencies, different filters or different wirings. 
Have you found out how the LNB supply is connected? There are basically 
2 obvious options: either the STV0299 OP0/OP1 pins or pins of the 
FlexCop. Maybe there even exists some code you can reuse.
