I installed the X3100 drivers from this thread:

They work amazingly in Lion, super fast graphics.
Still no luck with sleep tho. The system will go to "sleep", only to be waken up by ECH0/ECH1.
Other then that, I got a fully working Lion installation. My own Hackbook with built in 3g wwan. I'll recieve a Artheros wifi card next week, to replace the Intel one. Hopefully i'll have sleep worked out by then.
