I know that embedding CSS styles directly into the HTML tags they affect defeats much of the purpose of CSS, but sometimes it's useful for debugging purposes, as in:
<p style="font-size: 24px">asdf</p>
What's the syntax for embedding a rule like:
a:hover {text-decoration: underline;}
into the style attribute of an A tag? It's obviously not this...
<a href="foo" style="text-decoration: underline">bar</a>
...since that would apply all the time, as opposed to just during hover.

I'm afraid it can't be done, the pseudo-class selectors can't be set in-line, you'll have to do it on the page or on a stylesheet.
I should mention that technically you should be able to do it according to the CSS spec, but most browsers don't support it
Edit: I just did a quick test with this:
<a href="test.html" style="{color: blue; background: white}
:visited {color: green}
:hover {background: yellow}
:visited:hover {color: purple}">Test</a>
And it doesn't work in IE7, IE8 beta 2, Firefox or Chrome. Can anyone else test in any other browsers?
