Note that it doesn't crash, but the display never comes back.
The distinction is important, because you can take the machine
down gracefully by first doing <ctrl><backspace> to kill the
X server and then <ctrl><alt><delete> to reboot the machine.

If the screen is black, then I also occasionally have luck
with:
   a) Change the Virtual terminal to 1: <ctrl><alt><F1>
   b) Put the machine into standby:     <Fn><F3>
   c) Wake up from standby:             <Fn>
   d) Switch back to the Xserver:       <ctrl><alt><F7>

Check comment above, may help.

See separate thread "Thinkpad T40 screen goes dead under Red
Hat 9 .." for discussion about <Fn><F3> and suspend problems.
