I was thinking about a separate page for cameras already in autobuild but having known problems which could be solved by testing, like the above linked S5IS issue. Most people will just go to the download page -> autobuild, and not notice that there might be a more/less serious issue with the port...
This is something that's been on my mind too. I don't have a good solution though.
A notice on the cameras wiki page would be a start, something like "this port may have problems, see (forum thread) and post if you are can test". This would only help people who visit the camera wiki page though.
More ideal would be to flag it on the actual autobuild download page. I don't think hacki has time to re-work this, but he might be open to putting up a replacement if someone else came up with a shell script or whatever to generate it in the autobuild process. Then the "this port has issues" links could be managed somewhere in svn (in the camera directory or camera_list.csv I guess)
