it is.  very.  i've watched wad do it.  and redo it.  :-)
it might even be more complicated than that page makes it look!
i modified my own G1G1 XO a couple of years ago in a similar
fashion.  but i wasn't as careful, and the plastic case now has
stress cracks showing up in several places due to the force i had
to use to cram everything back together.  wad has done a much better
job of making things fit properly.

yes.  in theory XO-1.5 has the ability to wake on USB events.  it's
on my todo list to see if that can be made to work properly.

the laptops being modified by wad are proof-of-concept prototypes
to see how that sort of keyboard might work for deployments to
older students.  if they were to become "real", the keyboard
would not be connected via USB.

certainly i wouldn't choose the micro keyboard that we've been able
to fit into the XO case as an external keyboard if i had a choice.
it's useable, but still too small.  and it lacks a right-hand shift key.
