Re:GL_ARB_transpose_matrix redux?

The Squeak3D.log file gets appended onto, so you had several sets of startup stuff included.  The few lines at the end of each set seems to be the important part.  This is a lame Microsoft emulated driver that doesn't really do much:

OpenGL vendor: Microsoft Corporation <<< GLView reports "Intel"
OpenGL renderer: GDI Generic <<< GLView reports "Intel 945GM"
OpenGL version: 1.1.0
OpenGL extensions: GL_WIN_swap_hint GL_EXT_bgra GL_EXT_paletted_texture

and this is a much better one:

OpenGL vendor: Intel
OpenGL renderer: Intel 945GM
OpenGL version: 1.4.0 - Build 4.14.10.4446
OpenGL extensions: GL_ARB_depth_texture GL_ARB_fragment_program GL_ARB_multitexture GL_ARB_point_parameters GL_ARB_shadow GL_ARB_texture_border_clamp GL_ARB_texture_compression GL_ARB_texture_cube_map GL_ARB_texture_env_add GL_ARB_texture_env_combine GL_ARB_texture_env_dot3 GL_ARB_texture_env_crossbar GL_ARB_transpose_matrix GL_ARB_vertex_buffer_object GL_ARB_vertex_program GL_ARB_window_pos GL_EXT_abgr GL_EXT_bgra GL_EXT_blend_color GL_EXT_blend_func_separate GL_EXT_blend_minmax GL_EXT_blend_subtract GL_EXT_clip_volume_hint GL_EXT_compiled_vertex_array GL_EXT_cull_vertex GL_EXT_draw_range_elements GL_EXT_fog_coord GL_EXT_multi_draw_arrays GL_EXT_packed_pixels GL_EXT_rescale_normal GL_EXT_secondary_color GL_EXT_separate_specular_color GL_EXT_shadow_funcs GL_EXT_stencil_two_side GL_EXT_stencil_wrap GL_EXT_texture_compression_s3tc GL_EXT_texture_env_add GL_EXT_texture_env_combine GL_EXT_texture_filter_anisotropic GL_EXT_texture3D GL_3DFX_texture_compression_FXT1 GL_IBM_texture_mirrored_repeat GL_NV_blend_square GL_NV_texgen_reflection GL_SGIS_generate_mipmap GL_WIN_swap_hint

Both of these were from your post, I'm assuming from when you had different drivers installed.  You can see that the second one DOES list out the extension you were wondering about.
