Note that for Pharo there is a project from Mike Filonov (owner of pharocloud.com) which
was initially called "PharoNOS". It is also based on TinyCore Linux, here x86 based 
directly booting into Pharo. A description and an downloadable ISO is available on [1]. 
Runs fine on VirtualBox.

>From the name often people thought it was a project similar to "SqueakNOS" (but SqueakNOS boots
into Squeak and needed no Linux or other underneath as even the drivers were
written in Smalltalk). I guess therefore Mike renamed the project to "Pharocloud OS" now,
he also made the build scripts available on [2]. 

I also did some experiments with Pharo on the Pi - described in an article on [3].
The result was similar: directly booting into the Pharo environment/ a Smalltalk 
application - but on the Pi. There is Raspbian underneath. A video is available on [4].

However: if there is now some interest in having a fast and direct Squeak/Pharo booting 
         on the Pi maybe this could be a shared effort between both communities as well. 

Beside squeak-dev I therefore CC the pharo-dev mailinglist as well.
