 '''possible''', it's also pretty easy to implement:
 http://wordpress.org/extend/plugins/preserved-html-editor-markup/

 That's nor exactly true :) This plugin preserves '''some''' of the html
 code formatting/line breaks, but breaks pretty bad with other. Example:

 {{{
 <p
     class="some"
     id="else"
     style="margin: 1em 0;"
 >
 }}}

 That's besides the point though, the text editor doesn't have preserving
 white space and line breaks as priority (as they don't matter in html).
 The priority there is to keep the paragraphs flowing "naturally" and allow
 use of some html tags. There was a discussion in IRC about making it
 easier for plugins to add Code tab, trying to preserve line breaks and
 white space would be good for there.

 The above plugin also replaces (some?) TinyMCE logic when inserting <br>
 tags. If that works well in all browsers, why not make a patch and submit
 it to them.
