After Kernel version 2.6.18 the hdlc module was divided into a sub module per protocol.  It may be that you need to load the appropriate sub module for the protocol that you have configured.
Use the following command to ensure that the required modules have been loaded:

lsmod

Use the following command to check module dependencies:

depmod -a

If unresolved symbols are reported for farsync.ko or fsflex.ko  then check again that the right modules are loaded.delete these files. (They belong in the net directory, and the ones in misc are just left lying around, but are being picked up first).

If the farsync module will now load. Use the following command:

modprobe farsync

if no errors are reported use the following command to see if the module has been loaded:

lsmod

You should see the farsync and hdlc/syncppp modules listed.

To load hdlc submodules use modprobe or insmod on one of the following modules as appropriate:
    hdlc_ppp.ko
    hdlc_cisco.ko
    hdlc_fr.ko
etc
