Yes. Neither QtMoko nor Replicant images come with kernels that support the camera.
To test the camera, please use the Debian/LXDE image and the camera test script in

yes, that sometimes happens if the camera is installed. The camera is filling
the plastics case to the last µm. So if something is a little different (tolerances)
the AUX button is stuck.

Yes, you can use a tiny rasp to make a little more room for the AUX button to
move in the case. It is a little difficult to describe how it works.

There might also be other methods to twist the case a little (maybe inserting
a small piece of paper).

Their function is immediately stopped if the AUX button is pressed (which
is in your case).

If you have the boot loader and boot script in NAND, you can boot SD
cards without a FAT partition.

I am not aware of, but if someone works on it, please raise your hand!

Ok, thanks for these comments. We will integrate it into the GTA04A5 manual.
