Hmm. Doesn't old X work if you disable KMS? Either with "i915.modeset=0"
or by just compiling it out?
Also, glxgears is usually not a good way to verify anything. At least some
versions used to run the gears at the painting frame rate rather than some
fixed rate, and so "jerky" or not depended not on how fast it was
painting, but on whether the painting speed was some multiple of the
screen refresh.
The FPS output from glxgears should mean something, although quite
frankly, considering the simplicity of the thing, not a whole lot. I'd
suggest using some somewhat more real test (I admit to having used
"Extreme Tux Racer", which while not wonderful either is certainly better
than glxgears ;^)
