He should also put a BIG FAT warning with 256K pages. Those will -not-
work with most existing userspace. The maximum page size supported by
the current userspace ABI is 64K as this is the alignment requirement of
our toolchain for the various program sections.
(Note that uClibc last I looked was also still broken with >4K pages but
that shouldn't be a big deal to fix).
