I'm the maintainer of the application that provides these listings, and it's great to see them featured on HN. I'll try and reply to some of the comments, but feel free to ask any other questions.
Years ago, I ran a "Linux Incompatibility List". You might consider the idea of something similar - a list of things to avoid because they're guaranteed not to work with Linux.
Do you consider a Broadcom 802.11n radio "compatible" even when Linux runs it in g mode?
