had a look and in exit_car.S the cache gets enabled, so this would probably be ok to do, but i don't have any of the affected platforms to test. do you think that it would be a good intermediate solution to drop cpu/x86/cache and replace all x86_enable_cache calls with enable_cache calls? the only thing we would lose from that are the post code and the message on the console about this. i'd say that any of this should be done as a follow-up patch to avoid messy rebases
