As I wrote elsewhere, I haven't benefited from LEN0068-patched acpi_ibm
except for wifi/bluetooth/thinklight switch through sysctl and the few
other little things.

Is it suppose to do more than that?

That leads back to the original question still in the subject: is there
anything I can do to help support of LEN0068?

Is it different enough to warrant a fork from acpi_ibm?
Are there specifications supposed to be available somewhere?
