Comment 29 for bug 62135

Well, sort of. I rebuilt the package after adding "CFLAGS += -fno-strict-aliasing" to the Makefile in $(srcdir)/src/mesa/drivers/dri/i965, installed and restarted X. Afterwards, those "i915_dispatch_cmdbuffer failed" messages are gone, and both glxgears and GL screensavers finally run.

However, it doesn't seem terribly hardware accelerated. CPU utilization is up to ca. 15% just running glxgears, and there are still those "libGL warning: 3D driver claims to not support visual 0x5a" messages. glxinfo says "direct rendering: yes", though.
