Without card=n insmod option, the card is wrongly autodetected as
DVB-T200 (hence my confusion in the earlier thread), and as you suggest
an "Unexpected tuner type" message comes up - this with "options saa7134
i2c_scan=1" in /etc/modprobe.conf.local

"modprobe mt352" does nothing AFAICT, even when "debug=1" is added

I have emailed Murray Graham directly (address from that archive) but no
response as yet.

Thanks for your help so far, I have grabbed the mercurial source and am
now trying to digest it...
