Excuse me  yes it is possible to shrink offline an ext2 filesystem.

For the online grow kernel patch there are informations at:

http://ext2resize.sourceforge.net/
or
http://sourceforge.net/projects/ext2resize/ 

For the merge of the patch in the 2.6 kernel there are informations at:

http://www.kernelnewbies.org/status/latest.html
or
http://kerneltrap.org/node/view/716

but I can not find the patch.
