Now the tricky part is extracting supported device IDs from drivers in an automatic fashion :)

I imagine some symbol magic could be done for the general case so a tool could extract the IDs & the bus type (so it could work for PCI & USB which covers about 99.9% of the hardware in question).

ISTR there a few modules which call some blob to determine if the module is supported but I think it's quite rare (the 80/20 rule works for me here :)
