alecdavis:  When you next get a chance to try the new version of the
driver, could you edit your /etc/dahdi/system.conf and add

echocanceller=hwec,1-15,17-31


As of last week users will be able to switch between hardware and software
echocan without reloading the drivers.  We still need to update
dahdi_genconf to default to hwec if possible.
