Comment # 15 on bug 107928 from Vik-T

Someone might find this helpful: I managed to reduce the number of driver
crashes considerably by disabling "suspend" and "off" mode in X. 

Section "ServerFlags"
        Option "SuspendTime" "0"
        Option "OffTime" "0"
EndSection

In the last 5-6 days, the driver crashed only once and I managed to bring X
back without rebooting. For me, that's a huge improvement over the situation
before where I had to reboot 2-3 times a day.
