How I can read EXT4 fs?
I use colinux devel version + fedora 11 image and colinix says 'unknown fsext4 '

My guess is you need the colinux kernel recompiled to support ext4. For now my best recommendation would be to use ext3. For the most part ext4 is only has a significant benefit when dealing with large volumes of data.
Filesystem ext4 on kernel 2.6.25 was under development and should not use in a production system. The config option is CONFIG_EXT4DEV. You can enable it and rebuild the kernel and modules. But, be carefully! This was a very early version of ext4. Maby read only mount option is a good idea.
Ext4 was official enabled later in kernel 2.6.28, I found in http://kernelnewbies.org/Ext4 and in http://en.wikipedia.org/wiki/Ext4.
EXT4 is enabled as module in kernel 220.127.116.11 now
