I would like to know what the XML is for the simplest feature and that will register a Server Control in the GAC, and add it the safe controls section of the web.config for the SharePoint site.
My assembly:
MyServerControl.dll (MyServerControl, Version=1.0.0.0, Culture=neutral, PublicKeyToken=3249363c0f6f8c59)
I can manually add it to the GAC with gacutil /i, but I want to have the feature do this for me and also add an element to SafeControls.

a feature cannot add files to the GAC, that's a job for a solution. The solution can deploy your feature to the 12 hives, the assembly to the GAC and can add a safe controls entry to the web.config.
