 I looked at the file at the location you mentioned, but I don't think the
 current code in CVS matches whatever you are looking at.  The line numbers you
 gave don't match up.  Can you please either tell me what the CVS revision
 number at the top of the file you are looking at is, or look at the most
 current one, which is:
 /*      $NetBSD: trap_subr.S,v 1.64 2008/05/24 21:39:01 phx Exp $       */
 Then let me know which line numbers in that file.
