That and the development board. You are using a sheevaplug.
It is also likely that Andy's hardware does fixups for misaligned accesses.
It's an NXP LPC3250, ARM926EJ-S. I have no idea if the hardware is
handling the alignment issue but that would explain why everything is
exactly zero on that box's alignment error stats. Searching the
datasheet for 'alignment' doesn't tell anything relevant.
