This is an A4 then:
 root at neo:~# cat /sys/devices/virtual/gpio/gpio55/value

On my phone, with qtmoko-gta04 v48 and no tuning, I have three radio
* Speaker
* Earpiece
* Headphones

And Headphones is selected by default whereas no headset jack is plugged
in. I guess the problem lies in headset detection, then. Could this be a
hardware problem? In this case, is there a way to disable headset detection?
