It seems at least some Linux knowledge is needed... mine is almost nil 
:(. I did as follows:
- Downloaded      Squeak-     and from the link you gave.
- Decompressed the .tar.gz file
- Saved the .sh, the .tar.gz, and the uncompressed folder to a /Cuis/ 
folder in an sd card.
- Added cuis image, changes and sources to that folder
- Inserted the sd card on the XO
- Opened the Terminal activity
- su
- cd /media/*/Cuis

First try: Now, trying to run the installer (.sh) gives 'command not 
found'. Executing Squeak-4*.sh results in the full name printed (i.e. 
found) followed by: ': command not found'.

Ok. Let's try something different
- cd Squeak-* matches the folder name and changes current folder
- cd bin
- ls shows squeak and
- Now running 'squeak ../../imagename.image' gives 'This interpreter 
(vers 6502) cannot read image file (vers. 6504)'

Looks like trying to run the original VM bundled with the machine. cp 
squeak sqq to have it with some other name. doing 'sqq enter' gives 
'sqq: command not found'. cp to have this .sh with 
some other name. doing ' enter' gives ' command not found'.

Looks like the machine doesn't want to run any binary from the sd card. 
I guess there is some linux detail I'm unaware of... Please help me!
