olpc-dm/Xorg segfault only if during systemd boot

[James Cameron]

I'm interested in finding the cause; any such race condition that
prevents X startup may eventually occur depending on timing, so is
there some simple reproducer that we can apply to OLPC OS?

Where are your changes relative to OLPC OS?

What does the systemd journal say about olpc-dm service?

How do the journal, olpc-dm logs, and X logs differ between working
and failing case?

Where does gdb show the segmentation fault occurs?
