It could be some temporary mapping that goes away after a while, so that it doesn't show in /proc/<pid>/maps permanently, but yes, this of course can be tried.

Could please someone, who has access to affected hardware, provide output of

       cat /proc/`pidof Xorg`/maps
       lspci -v

commands, so that we can see if there is possibly some lethal overlap?
