Cheers Estel,

I realised that bq27x00_battery was also listed in /etc/modules.
So I vi modules and deleted the line contining bq27x00_battery to ensure it doesn't startup on reboots.

I enabled bq27x00_battery to get CPU temp from QCPUFreq. I am using this in conjunction with KP49 to overclock. But having rmmod bq27x00_battery and this module on disabled at startup, I have found that the program is still outputting a temp. So I'm happy as larry.

There's instuctions here on how to blacklist for anyone that is interested:
