Hello,

I have ASUS M3700N. As I understand it has the same bios as S1N and M2N. 
And I want to say, that starting from 2.6-test8 everything works out of 
the box. Before 2.6-test8 there was needed to apply a small patch like 
the following:

Now it is fixed in mainstream. After this patch everything works just 
fine. Before there was lots of problems with acpi routing, keventd, etc.

I also have information, that this patch cures problems with acpi on 
ASUS-S200N.
