you made me verify what i said but looks like i'm correct:

Router#sh ip int b
Interface IP-Address OK? Method Status
Protocol
FastEthernet0/0 unassigned YES unset administratively down
down
Serial0/0 unassigned YES unset up
down
FastEthernet0/1 unassigned YES unset administratively down
down
Serial0/1 unassigned YES unset up
down
Multilink1 unassigned YES unset down
down
Router#

both serial interfaces are down but the multilink reports 3 megs:

Multilink1 is down, line protocol is down
  Hardware is multilink group interface
  MTU 1500 bytes, BW 3088 Kbit/sec, DLY 100000 usec,
