Replying to myself, just to drop a note about an old and long time
ongoing problem which maybe affects some others here on the list:

With the latest updates from kernel 3.10.5 (vanilla), all my machines
are without any crash now, using SNA. (They still crash the same as
usual with standard UXA, though..)

For those who don't know about the different Intel drivers: F19
defaults to UXA, and you can switch to SNA by placing a file named
"10-intel.conf" in /etc/X11/xorg.conf.d which contains something like

Section "Device"
   Identifier "Card0"
   Driver "intel"
   Option "AccelMethod" "SNA"
EndSection
