I have had a look at the way the reference Philips Europa card is set up in saa7134-dvb.c and I see that DVB-T300 is missing one of the sleep functions - tuner has one, but the front end doesn't. Maybe there's more, but I don't know. Not sure what went wrong and when. I presume you know what needs to be done from this point onwards? Anyway, this workaround seems perfectly fine for now. Do you think there is any functionality I will be missing compared to using card=70? Thanks a lot for your help.
