Insert card pc layer calls hotplug hotplug loads vga driver pci layer calls vga driver vga driver generates hotplug event hotplug loads stuff (user policy) vga driver calls hotplugged drivers > I guess you need to build something into the VGA driver that gets the > PCI ID tables out of the various fbdev/DRM drivers and combine them > into a single table visible to hotplug.

The vga_device_register functions take a vga_driver object which is a PCI driver lookalike with an extra field of "type" so you can load DRM's, FB's etc > What if I have two identical PCI video cards.
