Right, very interesting. The first way works. If i'm in the OS, unload 
the dvb_usb_dib0700 module and then load mt2060 and load dvb_usb_dib0700 
I get :-

dib0700: loaded with support for 5 different device-types
dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software 
demuxer.
DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)
DVB: registering frontend 0 (DiBcom 3000MC/P)...
MT2060: successfully identified (IF1 = 1220)
dvb-usb: will pass the complete MPEG2 transport stream to the software 
demuxer.
DVB: registering new adapter (Hauppauge Nova-T 500 Dual DVB-T)
DVB: registering frontend 1 (DiBcom 3000MC/P)...
MT2060: successfully identified (IF1 = 1220)
input: IR-receiver inside an USB DVB receiver as /class/input/input5
dvb-usb: schedule remote query interval to 150 msecs.
dvb-usb: Hauppauge Nova-T 500 Dual DVB-T successfully initialized and 
connected.
usbcore: registered new interface driver dvb_usb_dib0700

but the second does not, I get the usual symbol issue with mt2060_attach().

Thanks
Chris
