Subject: [PATCH] modules: insert mods sorted

While there isn't a big difference between typing 'lsmod' and
'lsmod | sort', the module listing in Oopses isn't so easily sorted.
Attempting to search these quickly by eye for particular modules while
rapidly triaging bugs can be a pain. Sort the list and reduce the pain.
