The working card has:
01:06.0 0480: 1131:7146 (rev 01)
Subsystem: 13c2:0008
Flags: bus master, medium devsel, latency 32, IRQ 201
Memory at df000000 (32-bit, non-prefetchable) [size=512]
Whereas the non-functional card has:
00:09.0 0480: 1131:7146 (rev 01)
Subsystem: 13c2:0001
Flags: medium devsel, IRQ 10
Memory at ea001000 (32-bit, non-prefetchable) [size=512]
Looking at av7110.c I see the problem in the switch statement on subsystem_device
i.e. for my non-functioning card (0001) it tries to attach to an ALPS TDLB7,
whereas this card actually has the Grundig 29504-401 (as attached when 0008 is
seen and thus why the other card works).
You weren't kidding about the scrambled ids on these old cards ;-(
Looking back I can see that this card had been previously working on a version
of the Linux DVB drivers that was built ... *cough* ... about two years ago.
No surprise things have changed a lot. These old Technotrend cards are
practically antiques ;-)
All the best.
Stuart
