Oops, forgot to comment on the kernel patch I just sent.

A while ago I tried to enable the use of dcbz in the kernel to speed up
memcpy/memzero operations and ran into problems. After much research and
postings to the embedded ppc list, I came up with this patch to workaround
the problem.

The patch has been tested by 2 other people and it worked fine for them.
The 8xx maintaner has rejected the patch so far since it is questionable
if it is a overall performace gain.
