 enter ebook mode while the system is already suspended, so the OS wouldn't
 get a chance to do anything.

 I'm wondering if a "wake up and then go back to sleep" in this case is
 what you want to happen anyway.  There are probably other things you need
 to do when entering e-book.  Not ideal from a power standpoint but one
 extra wakeup won't make that much difference.

 > I think the right way to disable the keyboard and touchpad is to send
 the "f5" command to both the keyboard and mouse ports.  To re-enaable,
 send the "f4" command to both ports.  I've tried that general approach
 from OFW in the Windows suspend/resume path and it behaves the way I think
 it should.

 Unfortunately, this is a rather large amount of work.  The whole subsystem
 for kbc and mouse data is designed to shuttle data from the device up to
 the host and then back down.  There are not currently any hooks for the EC
 to insert a command into the stream(s).  Its a pretty thorny chunk of code
 to work with.
