The no sleep on lid close issue was only a problem in XP and prior OS's. Vista has the detection of the lid magnet built into the OS now, as every driver I have tried (and I have tried most all of them now) has enabled the screen to properly power off with the lid shut. Don't ask me how they managed to get this working thru the OS, but its there. I cannot explain however, the fact that you are having the lid not shut off with this driver - as it has worked everytime for me...
