Is there any particular problem you are trying to solve with this, or is 
it mainly for research/educational/curiosity reasons?

I've had this paper sitting on my desk for a couple of years, but I 
still haven't been able to find the time to read it, "Designing and 
Implementing Lightweight Kernels for Capability Computing" , buy Rolf 
Riesen et. al.:

http://onlinelibrary.wiley.com/doi/10.1002/cpe.1361/pdf

It lists a variety of kernels designed for this purpose, so you might 
want to take a look at it, and see if you can get the source code to any 
of them.

Also, what's wrong with Linux? Would a stripped down Linux kernel be 
suitable. One of the early selling points of Linux was it's modular 
design that allowed you to remove components to increase the performance 
and reduce resource requirements. Have you looked at just paring down 
the Linux kernel as much as possible?  This is something I've always 
wanted to do but never had the time.
