It works, it sees the two cores of my CPU and I the acpi command gives me info about the CPU, temperature, battery and cooling. The laptop also shutsdown by itself when I execute the shutdown command. Here's the output from 'dmesg | grep -i ACPI': http://codepad.org/KcqZMvCa The only problem left is that X starts slowly and doesn't shutdown when I exit Openbox, but that's has probably to do with the video driver.
