So:

SAA7146A GPIO1 -> TDA9819 STD
SAA7146A GPIO3 -> TDA9819 INSWI

Makes sense to use these two GPIOs, since they were used to control SCART
pins 8 and 16, respectively, and the new card doesn't seem to have a SCART
connector (or does it?). To complete the list, I presume the other two
GPIOs still have the same task:

SAA7146A GPIO0 is presumably still the Dual-Port RAM interrupt input
SAA7146A GPIO2 is presumably still the board reset pin (HIGH for operation)

So you'll probably have to write 0x50505010 to SAA7146A register 0xE0 for
DVB operation, 0x40505010 for analog PAL-B/G and SECAM-L, and 0x40504010
for analog NTSC-M.
