Yes, it is the firmware. AF9035/AF9033 firmware is aware of used tuner
and there is some logic inside firmware for each tuner, like calculating
signal strength and handling of tuner I2C bus. Same applies for
AF9015/AF9013 too where this has caused some notable problems - I have
asked few times if someone could reverse and fix that fw to behave better.

Feel free to try. I tried it ages back in 2009 but failed.
Someone should make some study of these firmwares and list what are
differences, supported tuners etc. That was discussed at the time af9035
was merged to the Kernel... As rule of thumb test first newest firmware.
Currently there is no 100% automated script to dump those firmwares from
the binary. AF9035 driver seems to contain multiple firmwares. Maybe
making script that finds and dumps all firmwares found from binary could
be handy.

Good!
