fwiw we recently implemented CONFIG_DISCONTIGMEM for parisc-linux to better
support N-class (and pa8800, which uses zx1). You are right that CONFIG_NUMA
and CONFIG_DISCONTIGMEM are a bit intertwined, but it can be made to work

For reference we are targetting these three memory layouts:
 * Astro: 0-3.75, 67.75-68, 4-64
 * zx1: 0-1, 257-260, 4-256
 * Stretch (N-class): 0-2, 4-32, 34-xxx

Astro and Stretch have been verified (up to 32GB, so 3 zones), zx1 
verification is still pending, but i don't see why it wouldn't work (famous 
last words? :)
