(d) is no longer an issue it seems, I've been running in this configuration for
weeks now and the two issues that used to appear no longer do.  I'm not
entirely sure it was our bug, and not just glamor doing something
inappropriate.

Personally, I'm all for using -modesetting on >=G80 and no longer plan on
maintaining -nouveau beyond bug fixes.  So, new hardware, and MST support will
require -modesetting unless someone else does the work.
