There's not a lot we can do with s3tc because of S3's patent/license
restrictions. 

Normally, OpenGL implementations would do software compression of
textures and then send them to the board. The patent seems to prevent
that, so we're staying away from it.

If an application has compressed texture (they compressed them
themselves or compressed them offline) we can download the compressed
texture to the board. Unfortunetly, that's of little use since most
applications don't work that way. 

If anyone from S3 is on the list and wants to talk to us about adding
open source support for s3tc to Mesa, we'd, of course, be interested.
