Not Linux 2.1.x . We dumped this feature.

It should be noted the authors of the networking code have
been trying to get request-route dumped for about two years.
You lose no functionality by dumping request-route and you can
do the same things far better with diald, which has no kernel
support. The security reason wasn't the reason we wanted it dumped
but its another very very good one. "man diald" ;)
