T60P install problem

[Neon Dion]

So I followed the guide in here, got everything working perfectly, almost, but when I close my laptop my screen then bugs out and wont go back to normal, then I have to reboot to be able to see anything, I was wondering if anyone knew how to fix that, or if its not fixable, I have an 8741 and I used the kexts that someone upped that had an 8741

Also if this is a known fix I apologize, but I ran a search and couldnt find anything, so any help would be appreciated...
