1. you *want* "ip route-cache cef"  (but that's not the root cause)

2. unless this has changed recently, you need to tell the router what
   sort of packets are "interesting enough" to bring up a dialup line.

   Put "dialer-group 1" in the "interface Dialer...", and add
   "dialer-list 1 protocol ip permit"

Put "login local" under "line vty 0 4".  If you don't have this (or
"aaa new-model" with the proper incantations) the router expects a 
"password XYZ" under "line vty 0 4".
