Create a custom ICC profile that describes the color the D1X "sees."

That's monitor gamma and has nothing to do with the gamma of the capture.
Photoshop 6 doesn't care. It can display a file identically on a Mac and PC
which have different monitor gamma's because it has a Display Using Monitor
Compensation feature that uses the monitor profile (that does know about
monitor gamma) to preview the working space file properly. It is therefore
OS independent.

IF that were true, then when you bring the file into Photoshop 6 on either
Mac or PC (lets say as an Adobe RGB tagged file), the image would look fine
on either a Mac or PC. Same with sRGB. IF the source of the camera data is
properly defined (something I would question based on Nikon's previous
dealings with ICC workflows), then the conversion into sRGB or Adobe RGB is
sound. With the original D1, Nikon claimed the camera's raw capture was NTSC
RGB which it wasn't.

Do NOT do that!

You are if you try and disable the correct behavior of Photoshop 6 to
accommodate Nikon by loading your display profile as your Working Space!
