	The simple reason is that I want to maintain the encapsulation of the
function.  It's 15 lines of assembly and it's the only thing stopping an
entire set of systems from working under Linux.  If I have to move the
function all the support code will need to be changed to deal with this and
then all the referencing code will have to be changed to know that of all
the other support functions this one is now "different".

	Basically, it wouldn't be pretty but it would work.  I'd rather maintain
the pretty organization if possible though.  ;)
