Flaw in RH 2.6 kernels. Not sure we're affected.

Linux kernel before 2.6.9, when running on the AMD64 and Intel EM64T architectures, allows local users to write to privileged IO ports via the OUTS instruction.

Not affected, all amd64 keyworded kernels in Portage are using 2.6.9 or later; closing bug.
