We have just split the AcpiSetFirmwareWakingVector into 2 interfaces -- one interface to set the 32-bit vector (and clear the 64-bit vector), and another interface to set the 64-bit vector (and clear the 32-bit vector.) See: http://www.acpica.org/bugzilla/show_bug.cgi?id=731 the new code is available at the acpica.org git.
