 James, Hartmut,
I have also had "interesting" PCI ID behaviour from my Compro VideoMate, on
FC4.
I have seen the correct PCI ID in dmesg, but I usually get 1850:0000 (or was
it 185b:0000?). I can't remember the exact ID. I've been using a
modprobe.conf workaround to get the saa7134-dvb module loaded.
My suspicion was that it was related to whether the machine was reset or
went through a power-down.

That makes sense! Can you please verify this?
I suspect that the board allows to remap the address of the eeprom that
defines the ID. This might be done i.e. with GPIOs of the SAA7134.

This shows the difference between a reset without removing power (warm boot) and a power down.

note: I have two carrds in my system, both report very similar results except that teh first is card 0 and the second is card 1. I have shown only card 1 below for convenience.

what is reported in dmesg as a result of executing modprobe saa7134 after a warm boot:
