Servoblaster PWM on pin 8 (GPIO14) not working

[lbaulig]

Hi,
I have a Raspberry Pi B+, does anyone know what I have to do to get pin 8 (GPIO14) to work as a PWM output?
I know that this pin is a special pin for serial connection, and I have changed both /boot/cmdline.txt and /etc/inittab accordingly to deactivate the serial connection, but it still doesn't do anything on that particular pin. All other pins are working just fine.

Greetings, Lukas

PS: Unfortunately, I cannot use any other pin, because the layout of some external hardware I have kind of forces me to use that pin, I would like to avoid breaking and resoldering that stuff.

I don't have a B+, but I do have Pi2 which I think has the same GPIO configuration. Pin 8 works for me with the latest code from git. All I did was "killall servod; servod --p1pins=8", and then echo 0= to /dev/servoblaster. I didn't bother with changing /boot/cmdline.txt or /etc/inittab for this quick test - I figured the serial driver wouldn't notice :)
