Lets first explain what is what and created by what:
1: When the kernel loads the support for lirc it creates through udev
   the devices /dev/lirc0 and /dev/lirc1 and through your own rule
   udev adds the simlink /dev/lircSerial. Without the card the last
   will point to /dev/lirc0 and with the card to /dev/lirc1.
2: Then comes in lircd (remember the extra d) lirc will create a
   socket (which is a kind of doorway) to the desired device.
   /var/run/lircd and a link to this socket in /dev/ /dev/lircd.
   You originally configured it through mcc and this program probably
   creates the file /etc/lirc/hardware.conf.
   By default this socket is called lircd. To prevent the new card
   from interfering we tried to give the socketfile it own uniek name.

This all seemed to work but have you tried if it worked with irsend -d
/var/run/lirc/lircdSerial?
