Pardon me if I am off-base here (I don't know much about LinuxBios), but I've heard rumors/threats of new BIOSes that incorporate DRM into the BIOS and won't allow non-approved OSes to run on them. Could LinuxBios be a way of protecting against this?
I'm not aware of DRM BIOSes which stop you running non-approved OSes; however if you do so, then you won't be able to run DRM-aware applications, because the chain of assurance from hardware (TPM) to BIOS to OS to Application is broken (and that's what DRM-aware applications look for before they'll let you play with copyright materials).
As far as I'm aware, all current DRM / TCPA / TCG implementations allow you to boot whatever you like, but if it's not a certified OS then DRM applications simply won't play ball.
Obviously if you start LinuxBIOS instead of the motherboard vendor-supplied BIOS, you simply ignore the existence of the TPM chip/s.
