ok the only thing i see wrong with my dell 545s is that when i hit Power Off in the apple menu.. it reboots which is rather anoying when i want to power off and walk away quickly

The chipset is
Intel P35/G33/G31
Intel 82801IR (ICH9R)

Im using the ICHx kext from the ideneb 1.4 installation

If theres a fix to make the power button work too that would be great but im just in need of getting the power off to work right
