I'm not quite sure what the error is, does vmware somehow rely on those
extensions? Just some comments to the specific extensions and what their
status is with the i915 driver.
Since the hardware doesn't do any acceleration for the vertex pipeline,
this could be supported potentially (but note that the corresponding
GL_ARB_fragment_shader extension would be very problematic, as the
hardware could not support anything but the most simple fragment
shaders), as it has to be done in software anyway. Maybe in the future.
This is supported if you install an external library (due to patent
concerns), or if you don't need the compression part but have
precompressed textures, it may work if you force it on with driconf
(unless you hit a software fallback path).
There is zero interest to support legacy vendor-specific extensions (and
afaik only drivers from one vendor ever supported this) which have been
superceded by more general vendor-independant extensions. Use for
instance ARB_fragment_program instead.
This is supported with a newer driver (was called i915tex, but now just
i915 again, there might be some trouble currently getting it to run
