I found an endianness problem as I mentioned on the other patch. But
I'm hoping you can get it to work without too much trouble.

I'd quite like to apply the patches that we currently have. The build
error currently prevents me going about halfway, but I suppose if we
can figure out how to avoid the microcode assembler include, we may be
able to fiddle the patch order and apply things that way.
