Thanks for all the great responses I have not tried Radeon Tool or xset 
(DPMS) because shutting the lid does turn the back light off.  For now 
when I suspend the machine I will run the standby script then shut the 
lid.  Charles with my X23 I have no garbled X problems, have you tried 
kernel 2.6.9?  It works great with no patches!  This is the first time I 
have ever gotten Suspend to Ram to work on Linux with out lots of 
patches and hassles.
