Upgrade the IOS to 12.0(7)T and use class-based wfq with priority
at output interface towards the peer, and wfq for other traffic:
access-list 101 permit ip <source> <mask> <destination> <mask>
access-list 102 permit ip any any
class sample
match access-group 101
class normal
match access-group102
policy-map peername
class sample
priority <bandwidth> <-- this is the guaranteed bandwidth to peer
class normal
bandwidth <bandwidth> <-- this is all other bandwidth
random-detect <--optional, use for wred
fair-queuing <-- optional, use for flow-based wfq
interface serial 1/0.1 point-to-point
service-policy output peername
This should do it.
