I'm really not smart enough to find out. Can you show me how to
make use of the aperture driver to lower the securelevel or to perform 
tasks normally forbidden when securelevel = 1 ?

I'd like to fix the aperture driver if possible, or to find a correct
solution for a device driver managing the memory mapping of the
framebuffer.

Thaks in advance.
