Ok, as I suspected, this is not a suspend error. Simply that I sometimes start an extra X server for
a fullscreen VNC session or to do presentations. Of course it ruins the SHM area just the same as
starting a dummy X server does to re-init the card if you use the default config file.
Interestingly enough, the answer was lurking in the suspend2 bugzilla :)
