I like the idea, but the lookup is a bit heavy and there's no caching.

Replying to myself ftw... I commited a pair of patches to my dev repo which convert the whole ADDED_MODULES array to a hash and then just "prime" this hash with the contents of the builtin file. It's quite a nice improvement overall: http://code.falconindy.com/cgit/mkinitcpio.git/commit/?id=1f1085e http://code.falconindy.com/cgit/mkinitcpio.git/commit/?id=5626743 d
