I can report some (limited) success with the m920x driver. It seems to be
trying to tune when I scan, although no locks on any channels, but it may
just be that I've got a poor signal. When trying Kaffeine there is some
fluctuation from the signal & SNR meters, & there is this output in syslog:
Jul  4 23:43:33 toshiba kernel: MT2060: IF1: 1220MHz
Jul  4 23:43:33 toshiba kernel: MT2060: PLL freq=537833kHz
f_lo1=1757750kHz  f_lo2=1183750kHz
Jul  4 23:43:33 toshiba kernel: MT2060: PLL div1=109  num1=55  div2=73
num2=8064
Jul  4 23:43:33 toshiba kernel: MT2060: PLL [1..5]: 5d 6d 30 f8 93
Jul  4 23:43:34 toshiba kernel: MT2060: IF1: 1220MHz
Jul  4 23:43:34 toshiba kernel: MT2060: PLL freq=537833kHz
f_lo1=1757750kHz  f_lo2=1183750kHz
Jul  4 23:43:34 toshiba kernel: MT2060: PLL div1=109  num1=55  div2=73
num2=8064
Jul  4 23:43:34 toshiba kernel: MT2060: PLL [1..5]: 5d 6d 30 f8 93

and so on...

However, the LED still doesn't light (does that indicate a bigger problem
than just the LED?) and I've still to get a video signal. I shall try to
test it on a known good signal, as there are things interfering with my TV
signal right now.
But it looks pretty hopeful - is there anything you can tell me about
maximising the signal etc?
I've attached my version of m920x.c
