I had a similar issue with intrepid. To be able to boot from the ext4 fs, I 
installed grub2 from jaunty. The error went away after compiling grub2 from 
source and coping only the ext2.mod to the grub dir. So there must be some 
later updates missing. I guess this is some fallout from 2.6.27/TESTFS or 
similar.
