This one is already covered by #330287, so let's track it there. In
general, its easier to deal with one issue per bug report.

I've included this patch in our sarge and sarge-security branches of
2.6.8. This patch is part of the patch-188.8.131.52 patch, which was
included as part of linux-2.6 (2.6.12-3). This patch was already
included in the upstream release of 2.6.13.
