Getting QEMU sorted out took a bit longer than expected (it didn't help that the Debian installer made the boot partition too small!), but I've now got a half-decent way of testing the big endian version. ArcEm runs a tad slow, but better than I was expecting.
The problem was a bug in the endian swapping code, but it would only affect the last few bytes of the transfer. Any transfer which ended on a word boundary would have been OK. The attached patch should fix the issue, and I've updated the source archive with both mine and Chris's fixes.
