^^^^^^^^^^^^
This chip and the RZ1000 are now widely known for this problem, and its
not FreeBSD specific.
There is a web page around that provides info on confirming its existance
(sorry I don't recall the URL, but try searching on RZ1000 or CMD640).
I have this vague recollection that the problem has something to do with
a "prefetch buffer" - if your BIOS has a reference to this in its IDE
settings, you might try disabling it....
