The Screen remains the same.. X, AGP & SMP

[Jim Cornette]

If someone encounters a display while using X that does not refresh and 
seems the computer is locked up. It is not locked up, but the display is.
It is still possible to switch to a terminal and safely shut down your 
computer. I think reboot or poweroff would safely shutdown or reboot 
your computer.
I filed this bug regarding the twice encountered screen lockup.

This is mainly posted for the two hours before the computer locks up. 
... The display, yes! Computer no!

I hope this reduces the chances of people just killing their computers 
when process are still running fine.
