[linux-dvb] activy dvb-t ALPS tdhd1-204A support?

I have also a AMC 570 with 2 dvb-t tuners. (activy dvb-t model
S26361-D1297-V300 GS2)
(Pcb has a print: ActivyAL BS 03601790A)
The chip is SAA7146AH. I opened the tuner tin box
and only chip that was visible was Epcos X7251D
Lspci gives me almost the
same than below, I think the important part is the 5f60 adress which
means that our cards have alps tdhd1-204a tuners. It seems that
there is no linux support for this card type yet.

I also attached .inf file from the original windows installation if
it gives any help. (I found it here
and it mentions my card)

I'd appreciate if somebody tells me if it is possible to
create linux support with a quick patch or not.

I have a Fujitsu Siemens Activy Media Center 530 with a dvb-t card.

lspci gives me this:
01:04.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
       Subsystem: Philips Semiconductors Unknown device 5f60
       Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
       Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
       Latency: 32 (3750ns min, 9500ns max)
       Interrupt: pin A routed to IRQ 17
       Region 0: Memory at fddff000 (32-bit, non-prefetchable) [size=512]

The saa7146 driver doesn't find the card - a no /dev/dvb* devices are created.

I found this in the archives:
however my device is 5f60 where his card had 5f61

I took the attached patch
and changed all occurrences of 5f61 to 5f60.

a "make reload" gave me this in dmesg:
saa7146: register extension 'budget dvb'.
ACPI: PCI Interrupt 0000:01:04.0[A] -> GSI 19 (level, low) -> IRQ 17
saa7146: found saa7146 @ mem e08ba000 (revision 1, irq 17) (0x1131,0x5f60).
saa7146 (0): dma buffer size 192512
DVB: registering new adapter (TT-Budget/WinTV-NOVA-T  PCI)
adapter failed MAC signature check
encoded MAC from EEPROM was
test_config / it = 0
budget: A frontend driver was not found for device 1131/7146 subsystem
You must set an I/O address with io=0x20c or io=0x30c

And /dev/dvb/adapter0 showed up!
But only these devices are created:
...so interface0 is missing (as the message "A frontend driver was not found"
says allready)

What could I do, to get my card working?
