I fixed that bug in the later patches, e.g., http://people.freebsd.org/~jkim/acpi_cx_native.diff However, it doesn't work yet. Please see below. > Sure.

Unfortunately, I don't have much time nor hardware to test, so it won't happen any time soon. Sorry. If anyone wants to pick it up from here, please feel free. Jung-uk Kim
