Comment(by cscott):

 Given mtd's explanation (thanks a lot, by the way, it was very helpful),
 my guess is that olpc-dm was originally written to be started from the
 initscripts (in tty0?), in which case it probably needed to grab a
 specific tty.  Around the time we moved to upstart, olpc-dm started being
 invoked from /etc/inittab instead, which gave it a specific controlling
 tty already and so it no longer needed to grab one.

 I'm going to add some of mtd's excellent explanation above to olpc-dm.c as
 a comment, and then commit the patch.  If we ever need to start a display
 on more than one vt, then we'll know what to do. =)
