Ummm, indeed, it doesn't work. The next surprise for me is that it
also doesn't work if we build/install reiser4progs rolled back to the
old commits. Whereas reiser4 support in grub also includes libreiser4.h
header:

It could happen that I missed something though..

I don't know such reasons. I'll merge your patches.
Double thanks for the "format41" branch :)
