Hi Peter,
I don't know if this helps, but if I connect an external monitor to the VGA output, the lid button works properly, and using the "debug" intel driver I see these lines at the end of Xorg.0.log

with no external monitor attached, the system hangs (black screen but for the mouse pointer) and after reboot in text mode I don't see anything in the Xorg.0.log .

I'll try again without external monitor with the ACPI stuff you posted.
