The original stv0299 driver from dvb-kernel checks for
the PLL chip at the I2C addresses 0x60 and 0x61. If a device
at 0x60 is found an SU1278/SH is detected (works with my
Lorenzen DVB-S (Technotrend Budget CI) board) if a device at
0x61 is found an Alps BSRU6 is detected.
Please get the stv0299 driver from the dvb-kernel CVS and apply the patch
attached to this mail. The frontend detection is now hardwired for
the SU1278/SH with PLL at 0x61.
We have to write a new auto probing routine because there are
SU1278/SH frontends with the PLL at 0x60 and 0x61 out there.
