I installed Lion, ran EDP 2.2 and all was good, didn't use sleep enabler as i know it caused issues with the 10.7.2 update. 
  
Installed 10.7.2 and now when i boot i have a black screen, i have read this is due to the DSDT, i have inserted the fix below BUT how can i perform this or resolve my issue from eiter -s on boot OR using the terminal in install mode OR running a linux live cd. 
  
Thanks for you advise
