I have seen this done in two different ways

  1. on callout failure, use apex to recreate your outbound xml, send it using httpRequest and parse the response xml to get your error message

  2. add an 'error' string field to the response class. You then do your webservice call to an intermediate layer which hides these exceptions and always returns to salesforce a 'valid' response.

both of which are just workarounds to salesforce limitations
