Instead of using a clunky switch-case paradigm, we now have all drivers being declaring two methods for their adapter class - create and probe. These methods are linked in each PCIGraphicsDriverInitializer structure, in a new s_initializers static list of them. Then, when we probe for a PCI device, we use each probe method and if there's a match, then the corresponding create method is called. As a result of this change, it's much more easy to add more drivers and the initialization code is more readable.
