intel xscale reference board... where in intel website?

Sure. See

Now, I have a question. In all the docs that I have seen, Intel insists that the PXA255 is a drop-in replacement for the PXA250, and in fact, they have pulled most of the support for the latter from their website.

However, in proofreading and DRCing my PXA255 design, I discovered that I had a set of pins defined twice, specificially D16, E15, E16 and F16. On the PXA250, these are all VSSQ, while on the PXA255, they are the NSSP/GPIO[81..84] signals. Is this hardware difference documented anywhere?

PXA250 did not have NSSP at all. Have a look here:
