DSDT for Dell Latitude E5520

[Chipsybg]

Guys, can you help me finish up my Latitude E5520 build?
I'm using a E6220 DSDT, which is apparently working, but I have some random artifacts using the HD3000, totally random long line across the screen.
The problem is that the 6220 is QM67 chipset, while my 5520 is HM65.

Thank you

Your signature says your current laptop is HP 4530s. Did you give up on the E5520 or did it work?
