I think that is an ambitious undertaking. I have taken a different
path, myself ;P

I modified GNAT's runtime to work with the microkernal that I'm
using. Once that is out of the way, you can compile your O/S
modules nearly like GNAT applications (some restrictions apply,
like the choice of startup routine). The GNAT RTL hack only took a
about 5 weeknights to get going. ;-)  All other O/S work is
work in progress.
