Comment 46 for bug 305979

Yup, that's correct. Patches are for testing only (i'm running with these patches now to verify that they actually do remove the drmWaitForVBlank bug).

Timo said earlier that libdrm 2.4.4 is ready, but it (and intel 2.6.0) is blocked by mesa not building against the drm headers provided by the kernel.. soon, hopefully.
