I've found an old PCI TV Card gathered from a Sony Vaio desktop PC. It look=
s really similar to a Haupauge PVR-150 or PVR-250 except it's recognized as=
 a Sony device in lspci.
ivtv default it to PVR-150 but it's probably more similar to a PVR-250. Is =
there a way to default it to PVR-250 instead of PVR-150?

Here is dmesg log:

I2C mapping looks different:

As you can see in the log, card as a "cx23416" (same as PVR-250) but ivtv s=
till load "cx25840". Could I get it to load "cx23416"?
