Since no one was able to test the provided patch, linux-2.6 2.6.18.dfsg.1-12
has been uploaded to unstable without it, which means fixing this has missed
the last kernel upload for etch r0.

That leaves this as a documentation issue for the release notes.  Here is a
proposed description:

  Some amd64 systems which have nvidia chipsets and more than 3GB of RAM
  seem to have an issue with 32-bit PCI access that may result in sporadic
  data corruption when accessing disks.  Because this problem was still
  under investigation by the Linux kernel developers at the time of release,
  it was not possible to include a fix for this problem in the etch kernel
  packages.  As a workaround, users running etch on such a system are
  recommended to add 'iommu=soft' to their kernel boot options.  See Debian
  bug #404148 for full details.

Thanks,
