Hi - I have OSX Lion running on my Nvidia 140m d830.  I installed with MyHack.  The only REAL issue I had was the sometimes black-screen boot up, was fixed by a properly patched DSDT posted by someone here.  But the other issue that is not a deal-breaker, but annoying, is that I can't get it show the battery icon in the menu bar.  If I go to energy saving in the system prefs, the box immediatly unchecks when I check it.  
  
Have tried (one-by-one, installed via KextWizard, then discarded if not working):  AppleSmartBatteryManager.kext 
VoodooBattery.kext 
ACPIBatterManager.kext 
booting with the -f flag 
  
So far no luck.  It works fine on battery, I just never know how much charge is left.  Any ideas? 
  
Thanks!
