My gut feeling is that this is exactly the same problem even if it
seems to be currently much more widespread and maybe not the same
code on a driver level is directly involved.  Something misreads the
current activity state and an unwanted power management kicks in.
It appears that you need a "lucky" combination of a software and
hardware, possibly down to a chipset level, to be affected. Drivers
got more "ambitious" and this is easier to trigger.  Note also
comments 11, 12 and 13 from bug 243022.  At the reverse side of that
coin screensavers started now to kill a screen power management in
toto - see bz #508886 and #509660.

Err..., I do not think so.
