Intel XScale NetBSD?

Hi,
   I'm very interested in BSD for embedded systems (such as the Intel  
XScale).  I haven't found much embedded literature for BSD in embedded  
systems.  Considering they comprise many orders of magnitude MORE  
"processors" in the world, having a BSD version tailored for embedded use  
would be very nice.  Have I missed something on the net?  I'm not sure  
where to start if I actually wanted to try the port myself.

   Any help or suggestions would be greatly appreciated.

Thank you,
Dr. David L. Mazzoni
