My understanding is that Russell is the only one left testing them, or at least
he was the only one complaining about a breakage lately on neponset.

I can wait several weeks for Russell to have a bit of time to try : I know it
will compile correctly at least for neponset, and I know almost all the code is
under #ifdef CONFIG_ARCH_PXA. And still I would feel far more comfortable if it
was tested, just as you.

Cheers.
