Well, I know this is a longstanding project, about 3-4 month I think, with
some help for the low layer (pmap and friends).

When I said 'This doesn't seem to hard to port', I certainly didn't use the
rigth work (I still have some problems with english), and this didn't
mean "it will work in 2 days", but "I won't need to change lot of things in
the kernel, others than the VM code".

I also wanted to do this by steps, of course. But I didn't plan to
make these steps available to the world. Perhaps I should ?

We could discuss about this when I get something significant running ?
