There is no option for I2C-gate, gate will be called every time when 
access to tuner is needed. If you already use MT2060 coming with AF9015 
driver it should work. I doubt that you are mixing em2880 driver and 
af9015 and wrong tuner driver is coming from em2880. But I am not sure. 
Could you make clean install to see whether or not it is working.

hg clone http://linuxtv.org/hg/v4l-dvb/
make install (root privileges)
replug stick
plug stick

It should work (hopefully)
