Unfortunately not.  There was nothing special about the DSDT changes
in that commit.  Likely the AML interpretter in Solaris is quirky and
one of the clauses in that commit (or some arrangement of clauses) is
confusing Solaris.  This is one of the unfortunate parts of ACPI -
despite the lengthy specification each implementation of ACPI is
different and it's painful to come up with AML code that runs on
multiple platforms.

You could try disabling acpi entirely.

You could also try iterating through the parts of that commit and
commenting out various DSDT entries until you find which one is
aggravating Solaris.
