OK, we're getting somewhere.  Thanks to the helpful folks of #radeon I
got s3tc to finally show up in glxinfo (though your suggestion of
MESA_EXTENSIONS worked as well).  I had libtxc_dxtn.so installed, but
somehow only the 32-bit version.

Anyway...  So the new build of vmware workstation 6.5 starts up now
without that specific assertion, but when I go to run dxdiag and test
direct3d, vmware hangs with a new one:

vmware-vmx: state_tracker/st_manager.c:483: st_context_notify_invalid_framebuffer: Assertion `stfb && stfb->iface == stfbi' failed.

As for MESA_GLSL...  shader_15.frag is the last one:

/* Shader 15 source, checksum 0 */
#extension GL_ATI_shader_texture_lod : enable
uniform sampler2D S0;void main(void) {gl_FragColor = texture2DdP(S0, gl_TexCoord[0].xy,dFdx(gl_TexCoord[0].xy),dFdy(gl_TexCoord[0].xy));}
/* Compile status: fail */
/* Log Info: */
Error: texture2DdP: undeclared function name.

And from vmware.log:
