Hmm, I misunderstood you. The TDA8060 is not controlled directly by the DVB 
drivers, so we don't _really_ need to worry about it. Its the tda5059 that is 
the chip we control. And the TSA5059 is definitely supported by the drivers. 
I have a DVB-S card here with the SU1278 on it, and it has a TDA8060 
(+tsa5059) in it as well.

Hmm, the one on mine is an SU1278/S. Note the missing 'H'- but the difference 
is supposedly just the orientation of the mounting pins.

SL1935 is a different PLL entirely - according to the stv0299.c source, you'd 
find that one in a SAMSUNG_TBMU24112IMB or a LG_TDQF_S001F.

Try enabling debug mode on the stv0299 driver with "debug=1" - see if there 
are any I/O errors in dmesg when you try to tune. It is *possible* they've 
changed the PLL address on your card for some reason.
