If you haven't seen it already, Linux Device Drivers should answer
many of your questions, and it's freely available online:
https://lwn.net/Kernel/LDD3/
If you write a template driver, you can put whatever vendor/device IDs
you want in the pci_device_id table, and then the driver will match
the device you care about. You might have to disable the driver (or
unload the driver module) that normally claims the device.
