Running 7 sounds good, but is there any particular (API?) reason that - Add support for setting the fan control mode to manual or automatic - Add support for adjusting the fan speed if the fan control mode is manual from acpi_ibm.c rev 1.10, was not MFC'd to 6-STABLE? If not, any chance before 6.3? Cheers, Ian
