I ran into a situation where I needed part of the page to render content from a user that did not need to be reformatted via reset.css. And from this thread it seems like others have too.
Here is how I am attempting to solve it. (Keep in mind I haven't fully tested it in Internet Explorer)
Basically I have created a stylesheet, that only effects elements below the class undoreset. Currently it only "undoes" certain HTML Elements, as they are the only ones I needed to "fix".
Example: Page without reset - Page with reset
