Comment(by dsaxena):

 Looked into this and the kernel has an LED subsystem that can be used to
 hook this in. Like most kernel stuff, documentation is rather lacking but
 what I believe we need to do is:

 - Add a mmcblock LED trigger event (maybe we can piggyback on the existing
 IDE  disk trigger?)
 - Add a driver for the XO that ties into this trigger (There's an existing
 GPIO LED driver, might be able to hook into it..)
