What you do looks quite ok.
Did you add an [index] section at the top of your mimeconf though ? Lines
like "application/x-rar = execm rclrar" should be inside an "index" section
(there are other sections in mimeconf, to define what icon to use, how to
group doc types into broader genres etc.)
Otherwise I can see really no reason why this wouldn't work, I'm quite
confident that rar will soon be a supported type :)
