I found it. The note about 176 MHz is on a single sheet of paper with Intel letterhead that came with the system. It simply listed what came with the Evaluation System plus the note Susan quotes. -Scott Perry Wagle writes:

You have Evaluation Systems based on the A-3 step of the IXP1200 Network Processor. Buried at the bottom of the cover letter included with your systems is the following:

"Also note, the IXP1200 Network Processor on this evaluation system runs at a core frequency of 176 MHz. This temporary condition is due to a lack of component availability used to design the evaluation board."

Intel officially supports 166 MHz and now 200 MHz versions of the IXP1200. Our first version of the Evaluation System run at 176 MHz as indicated above.

I don't find the "core frequency of 176" in the printed documentation that came with the systems, though now that you mention it, I seem to remember reading that line somewhere. Could you be more specific about its location? (I'm hoping to find other important information there.)
