Yes, I use qemu-linaro for those tests.

Is it useful ? Obviously for me, yes. It lets me test images in qemu,
and I don't need real hardware to run those tests. That means that
I don't depend on the hardware really working, and I am not hosed
if the hardware breaks down and I don't have a replacement. Plus,
of course, I don't need a lab with 90+ pieces of hardware.
