You do not have to have .conf file for a pci driver, since the PCI
nexus driver will create all the necessary properties.
You only need one if you want to supply additional (i.e. non-hardware)
properties.
What you need is to run (assuming your driver is called spm)
add_drv -i '"pci104c,ac10"' spm
Note, there is a double quoted device name wrapped with single quote.
