I'd worried about endianess while testing. I've been spending the last 2 
days trying to setup a QEMU powerpc64 image to run some regression 
testing but it's taking forever (combination of old P4 computer and QEMU 
giving me random errors from the cdrom drive).

I'll run it through the grinder in a bit.
