I was thinking more along the lines of;  Since I am testing a filesystem 
driver, to have a small test binary I can run and just feed a patch to (be 
it block device, or raw file) to test it can traverse, and read the contents.

But it would not be so bad to simulate that with some #ifdefs I guess.

I have no idea. I found the patches back in Dec, and it is not in the 
repository. Although, I have patched it into my tree on github, it might 
help merging it into uboot. It does appear to work, whereas my zfs does not :)
