Isn't that the other way around?

In the header loadu is using movups which is for unaligned data.

It doesn't matter though, I agree with what your saying and see that it could 
be a problem. Aligning the data wouldn't be a that big of a deal I don't 
think though, a simple attribute added to the var declaration (or is it 
definition... I never get it straight), it shouldn't change the data access 
in any other way than allowing fast loading to sse or mmx from what I read. I 
didn't read much though.
