Agreed. However, I recall purchasing a similar upgrade for my aging Acorn A3000 several years ago.

Did you have to remove a BGA though to fit this upgrade board? It's a pain to remove a BGA even with a proper SMD rework station. The empeg would definitely have to be sent off to get this upgrade done.

I don't know about the RAM - perhaps with the right choice of processor that wouldn't be neccesary.

The RAM on the empeg board is only 60ns so won't work with any of the IXP/PXAs. It's far too slow.
