Update #2

Happy holidays to everyone. The problem is located in atkbd.c . It was fixed a long time ago. I will get with them after the new year and see if they will patch it since it affects a project they are working on. If you would like to see both the acpi and the keyboard workiing. The new unbuntu kernel update has issues with these laptops. Use the stock kernel 2.6.35-22-generic add the following to the grub boot line. You need to attach a external keyboard.

apm=power-off nomce vga=771 intel_idle.max_cstate=0

Now once you boot with a external keyboard attached keep tapping the enterkey <This is very important it creates a response from the atkdb which initializes the internal and external keyboard.

It may be a little bit flaky with the unbuntu kernel. Your system may reboot a couple of times. This has been fixed in the test kernel. It works just fine with the stock knoppix 6.2.1 kernel. If you would like to test it out without reinstalling anything.

Regards and happy holidays
