I will have some time during the next days so hopefully I'll be able to explorr the possibilities. One that should certainly work is to create a very minimal Linux system that immediately starts up Squeak. Another would be to look at the non-Linux alternatives such as RISC OS and see how they are doing it.

Cheers,
Hans-Martin

The main complication is that the ARM is just the I/O processor on this
machine and it is the secret "GPU" that boots first and does all the
initialization. This has already been figured out for Linux in the form
of a binary blob, though I think there are enough details available to
adapt it for other uses. There is the option of having a stripped down
Linux under Squeak, like Dan Ingalls used in his Squeak Box
(unfortunately, http://www.fflinux.org where all the code was is long
gone):
