The following message appears repeatedly in the /var/log/messages, kern.log and syslog:

Evidently there is an updated ACPI entry; I have not tried it:
http://acpi.sourceforge.net/dsdt/view.php?id=417
(I am handling this machine remote, and don't risk recompiling the kernel and rebooting it right now...)
This is quite an inexpensive amd64 laptop, and I suspect that there will be more and more of them on the market; it would probably be good to get it supported out-of-the-box...
I should first prefix this with: I'm not completely familiar how ACPI works, or the legal issues involved with distributing modified versions of the ACPI implementation contained in the laptops.
I have the same problems with my Acer laptop. I'm not sure that this is something that can be fixed out of the box. The acpi implementation that is shipped with the ACER laptop is buggy, same as mine. So, first the installer or kernel would have to detect the laptop and then install the 'fixed' acpi. However, since I've fixed my ACPI, acer has shipped the same model and versions of my laptop with newer, less-buggy ACPI implementations. And my 'fixed' version does not work on these new laptops. I'm not certain that there are ways to detect the different versions of the same laptop, and then install the appropriate ACPI's, is there?
Additionally, does anyone know if there are there legal issues involved in distributing the fixed acpi file's?
