Ooh that sounds bad.  Can you check out
http://intellinuxgraphics.org/how_to_report_bug.html and file a bug at
freedesktop.org for this?  That way we won't lose it, and we'll have
all the info in one place.

Eric, do you know of any changes recently that might affect the
gem_idle warning Niel sees here?  Seems like in any UMS config the GEM
lists should be clear at VT switch time...
