It's not clear that the bug is actually with acpi. It's the most likely problem but it's not _certain_. My tests at fixing the "low-hanging fruit" with the replacement DSDT.aml weren't productive. However, this was the first time I even looked at a DSDT file so I could well have not done it properly.
