Current F11 failing to Suspend the display when the screensaver
(actually Gnome Power Manager) blanks the screen is a bug in Kernel
Mode Setting (KMS). The problem can be demonstrated with xset:
xset dpms force suspend ; sleep 10 ; xset dpms force on
Disabling KMS with "nomodeset" on the kernel command line allows
2.6.29.5 and up kernels to Suspend the display just as 2.6.29.4
kernels can with or without KMS.
