You mean, we don't need a xen12load equivalent, or a xen12load equivalent
can't work with xen 2.0 ?

Would be nice to have a ddb usable in dom0 :)

Hum, I tried to add "movl    %2,%%ebx;" before TRAP_INSTR, but this didn't 
help. I guess there's something else to be done to translate the code
in hyperviror.h to PIC code.
Anyway, if a xenload isn't needed any more, I'll give up on this and try
to load a kernel directly.
