function getKeyByClassName($className) {
	foreach ($GLOBALS['TYPO3_LOADED_EXT'] as $key => $data) {
		if (substr($className, 0, strlen($data['classPrefix']])) == $data['classPrefix']) {
			return $key;
		}
	}
	return false;
}

Now the only task is to set classPrefix to $GLOBALS['TYPO3_LOADED_EXT'].
