Linux Foundation Releases Blueprint for UEFI Secure Boot

The Linux Foundation paper calls Microsoft's plans "counter to the UEFI recommendation that the platform owner be the PK controller" and says that it is "a legitimate choice for an informed user to make voluntarily". Both papers suggest that all platforms which enable Secure Boot should ship in "setup mode" which would give the system owner control of the Secure Boot system. Initial startup of an operating system should then detect that setup mode and install a KEK (key-exchange-key) and PK to enable Secure Boot. The system would then securely boot that operating system. When a user needed to take control of their system's secure boot, a "reset" option for UEFI's keys would allow those keys to be cleared and a different operating system installed. Microsoft's Windows 8 could also be pre-installed in the same way; the UEFI reset would then unlock the machine for other operating systems.
