Please do something to make the original macros inaccessible so that they
can't be used inadvertantly or advertantly (if you haven't already).
Many other things in <*/param.h> that are actually parameters need this
treatment.  A sysctl call (not just a variable) may be the best way to
get the parameters even in modules.
