sounds like my problems with nvidia optimus. the 3.12 kernel contains bugs
around gpu/acpi/power-managment. i'm using the 3.13-rcX kernel from rawhide
which contains fresh fix:  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f244d8b623dae7a7bc695b0336f67729b95a9736
with this rawhide kernel optimus works fine with acpi pm events (laptop lid close+open).

BR,
Paweł.
