Whichever one works but s2c wouldn't require symbol decoding.  Maybe
we can simply add an option to tell it to just parse the oops and
output it in machine friendly format.  Oh, also, the patch does add
new information the module load addresses.  We should be able to add
those to the oops message in a compact form.

Thanks.
