Actually I don't know what exactly that would lead to: wold I get SHR 
testing or the current SHR unstable?

OTH, my current setup works (mostly) well and recently there were a 
bunch of people reporting problems with getting a GPS fix, and I don't 
want to go through that process again myself.

I would expect to exist some command line instructions (like dbus-send) 
to control suspend and screen on/off.
