of the device specified in 'string'. Added register mechanism and chained list to store the device name and pointer. Replace hardcoded debug info implementations for pic, pci and vga by the new one. - TODO #1: improve existing debug_dump() output and add more devices - TODO #2: add support for additional arguments and replace the NE2k print_info()
