Currently only 16kB works and only for 64-bit kernels. I'm planning to fix that rsn. 64K pagesize is extremly large for embedded systems of the size of the typical Alchemy system due to the memory overhead.

Old binutils (2.14 and earlier) didn't put enough alignment between code and data section, it this case a re-link with a newer linker is needed. Some userland applications hardcode a specific pagesize, typically 4kB, instead of querying sysconf(_SC_PAGESIZE). Those applications will need fixing.
