My Intel X3100 outputs this:
$ glxinfo | grep GLX_EXT_texture_from_pixmap
GLX_ARB_multisample, GLX_EXT_import_context, GLX_EXT_texture_from_pixmap,
FWIW the first line comes from the "client glx extensions" list, the
second from "GLX extensions", and the third from "OpenGL extensions".
FWIW some other interesting lines from glxinfo:
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) 965GM 4.1.3002 x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 7.0.1

Well, I did not do anything with my X, Intel driver, Mesa nor DRM, and
Compiz works here with stock Gutsy components (and that SKIP_CHECKS

My glxinfo says direct rendering is disabled, but I think that's because
I have compiz currently running:
direct rendering: No (LIBGL_ALWAYS_INDIRECT set)
I don't know about x86_64. I run the x86 version of Ubuntu (mostly
because I hadn't realized the version labeled AMD64 would run on my
Intel Core 2 Duo laptop back when I was installing it).

It might be worth investigating why GLX_EXT_texture_from_pixmap is
missing from your setup, but I'm pretty much clueless in that area.
Or you could try downgrading back to Ubuntu versions of the intel driver

It's easy to get used to eye candy. I switched to 16 bits per pixel
just so that I could get Compiz on an external 1280x1024 monitor with my
old Radeon 7500.
This sentence does in fact not have the property it claims not to have.
