No, these images are meant for NAND install. For USB/SD we'd need yet  
another image, OLPC used to provide ext3 ones.

People should be aware that this is a one-way street. Once you run  
this new Sugar version, the Journal contents will be converted to a  
new format. AFAIK it cannot be reverted back to the older format.

Actually, Sebastian, there should be a big WARNING in your  
announcements about this ...

Yes, that would be the only option to go back.
