Yes, version 1 superblock support is in 2.6.13. You need the latest 
mdadm as well.

No. 2.4 kernels do not understand version 1 superblocks. They only 
support 0.90 superblocks (which is what you've got).

You'll have to re-create the array using the version 1 superblock 
format. The existing 0.90 superblocks will continue to be used until 
you've done that.
