The only one of these cherry-picks that should have *any* effect with
your configuration is "exa: use CLAMP_TO_EDGE for RepeatPad", the others
only affect code paths which are not entered in default setups. I
cannot really imagine how this commit could lead to problems on
suspend/resume, but could you please try and revert it?

There's also the possibility that AIGLX is the problem (using the
experimental xserver-xorg-video-nouveau package with unstable's
libgl1-mesa-dri triggers AIGLX errors, as can be seen in your logs).
Can you please turn off AIGLX in the SERVERFLAGS section of xorg.conf
and test whether that helps in 1.0.1-4 ?
Cheers,
Sven
