Phoronix reports Intel pushes Open-source support for Ivy Bridge, you can read it over here.
Just as I had said two weeks ago: expect Intel "Ivy Bridge"
open-source Linux support to be pushed to the Linux 2.6.40 kernel. This
code was pushed today in preparation for the Linux 2.6.40 kernel. It
will land in a similar manner to Valve's Source/Steam native Linux
support coming soon, early AMD Bulldozer benchmarks, ATI/AMD's "Orka"
Linux driver support in the past, etc. Here's Intel's Ivy Bridge code
that enables next-generation hardware support.
