Could you tell us the long story? :)

According to this article:

"On the flip side, Intel believes it can use open-source drivers to gain
against Nvidia and ATI. The strategy parallels the chipmaker's earlier
move with wireless networking support
and it has won an ally in Red Hat. "Their partnering with the
open-source community is a pretty strong advantage," Stevens said.

Intel has new plans for its open-source graphics driver work, though
Hohndel wouldn't reveal details. "Our (graphics) drivers are open
source. We are bringing out some interesting new stuff. It's not
released yet," he said."
