This release represents the start of a long term effort by Intel to work with the X.org and Mesa communities to continuously improve and enhance the drivers. While these drivers represent significant work at both Tungsten Graphics and Intel, as our first release of this code, they're still in need of significant testing, tuning and bug fixing before they'll be ready for production use. We're releasing them now to demonstrate our ongoing commitment to providing free software drivers for Intel hardware.
The project website is located here. Of course, as a plus to the OSS community, they are releasing the source only – if you want a binary or preconfigured package, you'll have to wait for your respective distribution or someone else to craft one.
