http://code.google.com/p/nvidia-texture-tools/wiki/FAQ may be relevant:
"Can I use the NVIDIA Texture Tools in the US? Do I have to obtain a
license of the S3TC patent (US patent 5,956,431)?
"NVIDIA has a license of the S3TC patent that covers all our
products, including our Texture Tools. You don't have to obtain a
license of the S3TC patent to use any of NVIDIA's products, but
certain uses of NVIDIA Texture Tools source code cannot be considered
NVIDIA products anymore."
(I don't know what Debian's rules about patents are, but it looks like
there's already packages for e.g. libdevil which implements the same
compression format and isn't covered by anybody's patent license.)
