m68k is one example of an architecture on which the unstated assumptions 
in your patch would be invalid. Does this help to clarify what I wrote?

If Megasas raid did work on m68k, I'm sure it could potentially benefit 
from the theoretical performance improvement from your patch.

So perhaps you would consider adding support for slower CPUs like m68k.
