I suggest you get a copy of my tree by anonymous rsync from
samba.anu.edu.au::linux-pmac-devel. Look at http://rsync.samba.org/
if you need more information about rsync.

It could be just that the RAM is set for write-back caching and the
values are still in the cache. (Write-back caching is the default
when the data MMU is disabled.) You can use the dcbst instruction to
make sure the stuff you write gets flushed to memory.
