The board is still for sale, even though it's not recommended for new
designs.

But then, there are not that many boards for RapidIO development, so the
board is still very much in use by people who do this style of work.

As to the most of the other issues: I mostly used copy/paste from other board
configs to do fix up my board's setup. Can you recommend a particular board
config which can serve a style reference? Freescale's MPC8548CDS is even
less prettier than my stuff.
