The Intel settlement with AMD seems to cover the issue, but perhaps the Intel lawyers have another view. Intel could probably remove the GenuineIntel check without overly effecting their sales"
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
