HSRP isn't going to provide router redundancy. Let
routing protocols handle that. HSRP provides
redundancy for hosts default-gateway settings. Also,
you can't assign the same IP subnet to more then one
interface on a router (or VLAN on switch).
I agree with the other comments. Get another serial
line going to another provider on another circuit, or
ISDN, or 56k dial up depending on your backup needs. I
have seen people backup a frame PVC with another PVC
on the same physical circuit which isn't really
effective. 99.9% of the time the whole frame relay
circuit goes away (physical issue, frame switch
mis-config, etc).
