There are great difficulties in trying to have Linux provide support for
a closed interface in the core kernel.  On the other hand, I read this
on the PICMG web site:

Does this really mean that the spec will be placed in the public domain
(as in "freely copyable") after approval?  This seems in contradiction
to other parts of the web site.
