I poked around in R600OverlapCopy() and noticed that in the case where the offset between src and dst is horizontal, the simple all-at-once copy seems to work correctly.
For the case where the offset is only vertical, I've modified the line-by-line copy to instead copy in chunks equal to height of the non-overlapping area.
The patch has only been tested on a RV770, so I will claim nothing regarding other GPUs. At least for this particular machine, EXA is now snappy and corruption free.
