It principle, this should be triggered by the PCI detection of the card, but I can't access the VGA address range before the vga isa driver is initialised. How could this be done? With newbus? If the vga driver was newbusified, should I attach my graphic card specific driver to both the pci bus and the vga generic driver and let it be initialised twice with two initialisation functions and only one softc structure?
