Before getting too excited, however, this ETC2 support isn't a full implementation for texture compression on the hardware but rather is just immediately decoding the ETC2 data into RGBX data.
Even if these patches aren't the best, at least in time for Mesa 9.1/10.0 in early 2013 we should have proper ETC2 support for at least the open-source Intel driver. They really want OpenGL ES 3.0 in Mesa by time of the next release and with GLES 3.0 comes the hard requirement on ETC2 support.
