FC6-current for i386 has it right:

[root@sandman ~]# rpm -qf /bin/mount
util-linux-2.13-0.45.3.fc6
[root@sandman ~]# ldd /bin/mount
        linux-gate.so.1 =>  (0xb7f63000)
        libblkid.so.1 => /lib/libblkid.so.1 (0x4b607000)
        libuuid.so.1 => /lib/libuuid.so.1 (0x4b601000)
        libselinux.so.1 => /lib/libselinux.so.1 (0x49ce5000)
        libc.so.6 => /lib/libc.so.6 (0x00aec000)
        libdevmapper.so.1.02 => /lib/libdevmapper.so.1.02 (0x49cfe000)
