The use of /sys is an option too but it is 2.6x specific. The same holds for
libsysfs and I'm not sure if everyone has the library installed. Parsing of
the devices file is very easy and the file format has been the same for a
long while (atleast from 2.2x to 2.6x). Each line just contains the
device/vendor ids, pci device class and everything else we might need. In
case of /sys a lot of dirctories/files need to be checked for detection
whereas for /proc/bus/pci/devices only one simple file needs to be checked.
