Ok, I wrote a new patch for README and a missing space in wortel/wortel.c
By the way, does the fact that nobody noticed mean that I'm the only one 
who sees this error (unexpected page fault)?  I didn't see what was 
causing it yet.

Ps: cvs diff was doing weird things, I got a load of "? filename" entries 
in my patch file (which means they went to stdout, not stderr).  Therefore 
I'm not sure if this is exactly how the patch should look.

ChangeLog entry:

2003-09-18  Bas Wijnen  <address@hidden>

        * README: Added an example grub configfile and info on how to get 
        and compile L4.
        * wortel/wortel.c (serve_bootstrap_requests): Added a space in
        error message.
