  I didn't found that one.

  Since you insisted writing an ELF loader isn't too difficult, I invested
  some time to explore this area using the vlink sources as a start ;-)
  After reading the FreeBSD manpage about elf, the vlink elf32 headers and
  the NetBSD loadfile sources, I was able to write some code that can parse
  and load an ELF kernel. However, there seems to be a problem: I could only
  boot the 1.6 ELF kernels into NetBSD without SetPatch beeing run. AFAIK,
  this is different to earlier releases of NetBSD/amiga that required SetPatch
  because of the 68060 (I know that the kernel can detect a 060 itself now).
  I can boot NetBSD with a private 1.5 kernel with SetPatch executed. I diffed
  locore from 1.5 and 1.6 but it seems to me that there isn't a change that
  could be the reason for the 1.6 kernel not liking SetPatch. I am going to
  check this issue after I installed 1.6 some day...

  Before I try to integrate my code into loadbsd, I would like to know who
  much interest in such a loadbsd exists.

  Gunther
