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.
