Whoa! I really didn't expect that to actually do anything. :-O 
You're a genius!
I've tried multiple suspend-resume cycles, with plugging out and in the
external monitor several times, and no visible glitches and no suspicious
kernel or application logs. Only kernel complaints were about the failing EDID
requests to the external monitor (which tends to happen when you unplug it).

If I'm not mistaken this is just a workaround however, right? We still need to
find out why "nvbo->bo.mem.mem_type == TTM_PL_TT"?

BTW: Thanks for your explanations about the nouveau buf offset! After reading
it a few times I'm now pretty sure I understand roughly what you are doing. :-)
