 I currently use genext2fs, followed by  tune2fs to add the journal and 
e2fsck to fix the incorrect FS version  number.  But it's extremely 
inefficient, especially since genext2fs first builds the filesystem in 
memory before committing to the output image.  Not good when you want to
create a 500GB partition :-)
