thanks for the link. but even if you use jquery with the no conflit mode with prototype, you must include jquery.js before prototype.
see http://stackoverflow.com/questions/2830510/jquery-noconflict-not-working-in-ie8-only is it to late (for 5.2) to propose evolution on CoreJavascriptStack for - adding prototype only if it's needed - set the order of core stack when using more than one toolkit ( jquery before prototype) - add core stack required when needed by a component (kind of @ImportCore)
