Not at the moment. However, there drivers for AMD, Intel, and nvidia chips as well patches for a number of ARM SoCs that are in the process of moving upstream. Also, Matt Turner wrote a KMS driver for 3D labs glint hardware that is pretty simple (single display controller, single DAC, etc.), however it hasn't been merged upstream yet. http://code.google.com/p/google-summer-of-code-2010-xorg/downloads/detail?name=Matt_Turner.tar.gz&can=2&q= His kernel git tree was on kernel.org so it's down at the moment, hence the link to the tarball.
