Red herring. It's not very nice for *applications* to not indirect through a driver, but if that driver is in userspace or kernel space is irrelevant. Incidentally, "applications" here include a lot of the parsers that produce /proc output. /proc/pci is occationally handy, but it is also an example on why you shouldn't do data reduction in kernel space unless you can avoid it. Now /proc/bus/pci is available and contains all the data, however.
