The well-known graphics driver development company,
SciTech Software, are closing on releasing a beta of their Linux port of their
SciTech SNAP Graphics for Linux. These drivers replace the 2D XFree86 modules for a large number of graphics chipsets. SciTech claims that their latest beta drivers have shown up to 12-15% faster 2D performance than their XFree86 counterparts (for some chipsets). In the initial final release, accelerated 3D via DRI won't be supported though.
