I say: Go for CompactFlash on the PCMCIA port instead of the DiskOnChip.
They are cheap and they work great.

We use it here.

I tried linux on a 823 yesterday and it works great!
The cpu core is the same as 850 (not 823e though).

As I said before - try a RPX LITE 823 from embedded planet.
I've got one here!

Then you can run Linux on it and try it out if it meets
your performance demands before you make your own board.

The 860/821/823e has bigger caches/mmu which will give you
better performance.
