With all due respect, in traditional monolithic, own-address-space kernels, they
directly relate in that the kernel *defines* the driver architecture/API. Even
though
jjos+decaf is NOT a traditional kernel
jjos+decaf is NOT a traditional kernel
jjos+decaf is NOT a traditional kernel
jjos+decaf is NOT a traditional kernel
jjos+decaf is NOT a traditional kernel
jjos+decaf is NOT a traditional kernel
the driver architecture absolutely *still* relates to jjos+decaf. I think
(based upon my reading of your email), the rest of your message reinforces this
view...

Having said that, a couple of points... I *still* think we ought to satisfy your
two needs by using the JavaOS API as defined in the "Device Driver Guide,"
available at the following NEW URL (the old one now gets redirected to a place
without the documents):
http://developer.java.sun.com/developer/products/JavaOS/TechDocs/index.html
BTW, please notice that I think you can also DOWNLOAD (?!?!?!) JavaOS from this
page! (The page info says it was last modified on the 7th...)
