This has already happened with Windows 8 verified hardware. If you want to run another OS, you (or rather, the OS maintainers) have to pay the $99 Microsoft (ed: VeriSign, see below) tax to get a Microsoft-signed bootloader and kernel. (Fedora has already done this.) A decent write-up is here with some comments from Linus: http://www.zdnet.com/blog/open-source/linus-torvalds-on-wind... It's kind of disturbing when the main reassurance is "Hackers will get around it. Probably."
