I am afraid I don't have a solution for you, but I can tell you that my
sony behaves the same, and I heard from some other people that have the
same problem.
S3 is still quite experimental and is much more difficult to implement
then S4 since it is much more machine dependent.
Can't tell you though if fixing the dsdt table can solve the problem.
As for resources, haven't found them yet, but if you go to the acpi page
at http://acpi.sourceforge.net/ they some links on the subject that
supposedly can lid you to the aml language specification. Haven't found
them yet and didn't have time to look.
