Lid close/opening problem on T60p

[zillac]

I have a T60p with firegl v5250, installed Leo4all v3 updated to 10.5.4

The lid close/reopening doesn't work on this system.
On lid close, the system doesn't go to sleep, which is alright.
However, on reopening the lid, there's only squares of different colors and lines and TWO stretched mouse cursors.

I can't find a solution now, but I guess it's the gfx driver.
If anyone has a working setup, please post your gfx kexts.

Thanks in advance.
