The modesetting xorg-server driver works fine, and has been working fine
for quite a number of years. It is the driver used by default, in the
default set up. You need to explicitly install another xf86-video-*
driver to get something else. It also should give 3D acceleration (and
has always, to my knowledge, done so). If you, or anyone else on the
mailing list, have problems using it, it is most likely a bug.
I've been telling people this on mailing lists for a long time, and as I
said before, it is the default configuration. I don't know what else to
do to squash rumors like this. It is even stated on the graphics wiki
page that you don't need for instance xf86-video-intel when using drm-kmod.
