Revision Missing

[kamikaz1]

I just recently acquired an e6850. I ran cpuz to check that it was so. Everything came up fine except in the box with the "Revision" code was empty (and Revision was written in grey as opposed to black). Is it something I should be worried about? Or did something go over my head.

Thanks in advance to anyone who can shed some light.
