With XAA acceleration support having been removed from X.Org Server 1.13, an independent developer decided to bring the more-modern EXA acceleration support to the vintage xf86-video-r128 driver. Connor Behan implemented EXA for the Rage 128 driver.
The R128 EXA support was merged but only yesterday was the driver formally released rather than this 2D support living only in Git. The xf86-video-r128 6.9.1 driver adds in the EXA support, fixes support when building without EXA, fixes things with XAA now gone, and a couple of other minor fixes.
The driver announcement can be found on xorg.
