  I first tried this with the 3.2 packages from ubuntu hardy, but I also built
the tools from pristine xen sources and saw the same behaviour.

  This isn't a xen-specific bug.  The "bug" is that the code used by pygrub,
which appears to have been largely lifted from grub, can't read from a 16k
block size UFS/FFS filesystem; in fact, it appears that the 8k block size
is hardcoded in the code and no attempt is made to determine the actual
block size of the UFS filesystem.

  If you're interested in seeing the bug in action, you can download the
disk image(s) and a little script to trigger the bug from here:
