Subject: lmw and stmw instructions not used copy functions

Hi
I noticed that the lmw and stmw instructions are not used in copy_page(), clear_page() etc.
Aren't these instructions faster than a bunch of lwz/stw?
I assume they are inappropriate for some reason, but I would like to know why.
Would they work on 8xx?
