glxgears is not a benchmark, but if you're having similar issues with
real applications: How much aperture space is available for the DRM
memory manager? I recommend giving it as much as possible with Option

The i915tex driver doesn't care about this, it always uses batchbuffers.

That's probably due to DGA mouse being broken since input-hotplug.
Daniel Stone told me on IRC it'll be fixed, but I don't know when. In
the meantime, setting the environment variable SDL_VIDEO_X11_DGAMOUSE=0
helps somewhat with SDL apps, but there are intermittent 'wraparound'
effects which make it mostly unusable with anything that really needs
relative motion.
