To do edit
Missing from both versions are: Mesa (computer graphics) and Advanced Linux Sound Architecture.
Also please note, that there are Wikipedia contents for free and open-source device drivers, e.g.:
- Free and open-source graphics device drivers
- Free and open-source device drivers: audio
- Free and open-source device drivers: IEEE 802.11
- Maybe Lines of code could be used to illustrate the size/extent of a library.
