Those two filesystems are /proc and /sys. sys is a little more organized than proc and newer, but not as user friendly. So it is a little bit better for programmers and to avoid parsing.
If you want the information from the sys filesystem (which lspci parses (see somefile that is outputted by

So to get the irq for eth0, you can just:
