What about using the *.dds format to store textures?
It supports S3TC texture compression and a plugin for gimp can be found here:
Yes, it is a format from Microsoft, but the necessary algorithms are from S3TC
which are part of OpenGL today:
It's in GL_ARB_texture_compression and GL_EXT_texture_compression_s3tc.
All what is necessary is an OpenGL driver with S3TC texture compression.
