Very excited to see this! Since I've been working on something similar for cryptsetup, I am looking forward to trying this out. It is also great to hear that this works with TrustedGrub. Since TrustedGrub is based on Grub 0.97 (and is not compatible with Grub 2), I've been installing Fedora 15 and then upgrading to Fedora 16 and then 17. It's tedious but it worked for me. I would be interested if someone has a better way of doing this. Again - thanks for tpm-luks!
