There seem to be no good wiki dealing with computer hardware, so I have started a small wiki of my own, under the Creative Commons Attribution-ShareAlike 2.5 license. The wiki try to have information about all kinds of computer hardware, and specifically Linux-support: www.hardware-wiki.com.
I agree to multi-license my eligible text contributions, unless otherwise stated, under Wikipedia's copyright terms and into the public domain. Please be aware that other contributors might not do the same, so if you want to use my contributions in the public domain, please check the multi-licensing guide.
