After I told him which exact bitmask to use on a T43 to test
hotkey_source_mask, his test results can be summarized as "I could see
no difference in behavior", which is *exactly* what I expected to
happen.

If anything went wrong with the thinkpad-acpi NVRAM code, you'd notice a
very large change in behavior (typical: hotkeys don't work, less
typical: random hotkey keypresses, hotkey press bursts, low responsivity
of hotkeys).
