Well, since the demise of S3 (I do not remember who bought the name) the
status of the patent is unclear (from what I heard, nobody really knows a
lot whom to contact to get any details).
But well, either it's a hardware only patent and, in Wine, we have no issues
at all. Either it's a software + hardware patent and we can use the code in
Wine in Europe.
Our plans to support this was to write some library (shipped outside of Wine
of course) that would be dlopened at run time and provide S3TC
decompression. Note that, in the D3D7 code, we first need to do some basic
ground-work to support this (the main blocking point is not really S3TC for
