Under Preferences>Saving Files, change the Image Previews to Never Save, and run a batch on the image to re-save.
Can't run a batch to do that, you say? Sure you can. Get the batch enhancement here:

Isn't exactly the solution, but will be quicker than doing it manually. Get all your images in a folder and batch them using Channel Mixer TIFF -- make no changes on the mixer and save. You could also try the lowest sharpening.
I could be coaxed to add something to this set or create a utility set...and then again, you can possibly record your own using a PS6 demo, which I believe can be located on Jumbo.com.
That help?
