My trusty soekris 5501 has an AMD Geode LX, which (AFAIK) is still only i586. It seems it is missing one instruction (NOPL) from being a full 686 chip :)
gas won't emit NOPLs for 686, so you should be safe: https://gcc.gnu.org/ml/gcc/2010-08/msg00194.html "6. Don't generate multi-byte nops for i686. PR 6957." -- Jakub Wilk
