Thanks for working on this.

I have upgraded to Linux 3.8-rc7 and xf86-video-intel 2.21.2 on my ThinkPad
X200 (Intel GM45) and on my workstation (Sandy Bridge GT2).

On my X200, I can use the TearFree option without any side-effects. If I enable
it on my workstation though, the result of terminal commands such as ls -hl or
ps auxf often lags — the lines appear one after another, just like on a serial
connection. Just wanted to let you know in case you were not aware of that yet.

Let me know if you need any more details.
