Please stop top-posting.

The problem is that we have no way to bind a PCI ID to a driver before the 
driver is loaded.  We don't have a database anywhere saying "this chip id 
means i need this driver".  Clearly you as a human can look at the pretty PCI 
name and know, but the server isn't that smart yet.  What we'd want to do is 
put that list in the driver itself, so when we first dlopen the driver we can 
ask it what PCI IDs it supports.

And in fact we have all the necessary information in the drivers already - 
since they all have to check for supported chips somehow - it's just a matter 
of factoring that out into a common data structure and teaching the server to 
read that at module open time.

The problem here would be stupid buses like ISA, but I'm perfectly willing to 
tell people insane enough to use ISA video cards that they need to explicitly 
specify their driver or else be stuck with vga(4) or vesa(4).  I think pretty 
much every other bus type (maybe excluding VLB) is capable of sane
