I'm thinking dynamically remap video RAM pages for Acorn kit with RAM or VRAM for speed.
This is now implemented and working for ARM610/710 and RO3.5 thru 3.71, however how can you determine the page size of screen memory reliably?

On a StrongARM for example, the screen memory pages are a different size to the value returned by OS_ReadMemMapInfo

EDIT: Ignore this question...I was mistakenly testing on the Kinectic, so RO4 rules apply.
