Yeah, it sucks. Why are these companies so uncooperative? I have a Clevo laptop and I actually emailed them asking for documentation or some kind of help. They replied with an Ubuntu help page. I had to reverse engineer it in order to implement some features on Linux and I didn't manage to figure out everything.

It's very hard work and I have immense respect for people who are able to reverse engineer entire systems. There would be no need for this activity if companies just played nice but since they don't I'm glad that there are people out there doing this work.
