A number of years ago, I was playing with the following C 
based microkernel, combined with my own Ada code:

http://rtmk.sourceforge.net/

It hasn't been maintained since 2002 but could still form a 
start.

I actually had some Ada code linked into it, and it booted up 
ok.  Today with the availability of Virtual Box, this sort of 
development should be much more convenient now.

My plan was to get something working with added Ada modules 
and then gradually replace the rtmk C code with Ada modules.

But I had to abandon that work because it is a very time 
consuming pursuit. I have far too many other priority things 
to do. But it was very fun at the time. I might just have to 
dig it out again and try it in Virtual Box, for fun. ;-)

My suggestion is to open source your effort and work on 
selling support instead. Or adopt a Trolltech (Qt) approach. 
Getting anyone to actually buy software today is an extremely 
tough sell.
