James Bottomley just published a description of the Linux Foundation's Secure Boot plan, which is pretty much as I outlined in the second point here - it's a bootloader that will boot untrusted images as long as a physically present end-user hits a key on every boot, and if a user switches their machine to setup mode it'll enrol the hash of the bootloader in order to avoid prompting again. In other words, it's less useful than shim. Just use shim instead.
