This isn't so hypothetical. I ran into problems trying to install an "unsanctioned" mini-pci wireless card in an IBM T30, only to find that the BIOS refused to allow me to boot into an operating system until the card was removed. I was not a happy camper. If IBM is willing to do this at the BIOS level, what's to say that a video card manufacturer isn't willing to do this for their MPEG/2 encoder (loadable) firmware? Anyway, it sucks and it very non-free. -- Chad Walstrom <chewie@wookimus.net> http://www.wookimus.net/ assert(expired(knowledge)); /* core dump */
