+\item[footnotes] To enable (partly) the linking of footnotes hyperref redefines or patches various commands, in part package dependant.
+\begin{itemize}
+\item hyperref redefines \cs{@xfootnotenext}, \cs{@xfootnotemark}, \cs{@mpfootnotetext},
+    \cs{@footnotetext}, \cs{@footnotemark}.
+    If \xpackage{tabularx} is loaded it changes \cs{TX at endtabularx}. If \xpackage{longtable} is loaded it changes \cs{LT at p@ftntext}.
+    If \xpackage{fancyvfb} is loaded it redefines \cs{V@@footnotetext}. It also redefines \cs{footref} and \cs{maketitle}.
+    
+\item \emph{All} those redefinitions can be suppressed by defining \cs{hyper at nopatch@footnote}. Be aware that this can suppress links but also make unwanted links appear.
