I realize this can't be easily changed because usb_hcd_pci_probe() takes the
pci_device_id pointer as an argument, and expects id.driver_data to be a
HC driver pointer.

So this turns out to be a question for Greg and Alan:

Would it make sense to change usb_hcd_pci_probe() to take a HC driver pointer
as an argument instead of a pointer to pci_device_id?
pci_device_id pointer is only used to extract the HC driver handle.
This way the driver_data could be used for, well, driver data.

That seems like a good idea to me.  There aren't very many drivers that 
use usb_hcd_pci_probe(); changing them all should be fairly easy.
