I would consider this a worthwhile addition to the kernel (and lspci). 
It would be nice if lspci could display what driver had claimed a 
particular device, and which devices were unclaimed by any driver or 
otherwise had an error that prevented initialization.

I don't have enough experience to gauge how invasive this would be, but 
I'd be happy to contribute towards it if practical.

Cheers,
Dan
