Yes, the <RSS_AUTODETECT_LINK> and <ATOM_AUTODETECT_LINK> tags were both in my default "simple" template, but neither of those gave me the rss feed icon as mentioned. i had to manually put the real url in like shown below.
PHP Code:
<link rel="alternate" type="application/rss+xml" title="hiimseth.com rss" href="http://www.hiimseth.com/index.php?x=rss">
