I've added a comment with a few details on the matter at http://forums.lenovo.com/t5/Linux-Discussion/S10-2-Wrong-Clockspeed-ACPI-Table-Error/m-p/175100#M1616.
You may want to try the same techniques to isolate the problem and make it a stronger case for Acer support.
Meanwhile I feel ashamed keeping this bug open on Ubuntu when it's purely a h/w vendor fault. I suggest closing it with an appropriate status.
