Yep, here's mine:

:~$  glxinfo | grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

again, here's mine:
:~$ glxinfo | head
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
    GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
    GLX_EXT_texture_from_pixmap, GLX_ARB_multisample, GLX_NV_float_buffer
client glx vendor string: NVIDIA Corporation
:~$

Thanks for your help again Yan. I also tried letting the nVidia util set 
my xorg.conf settings, but the results of that were the same (10fps in 
glxgears), so I switched back to the xorg.conf that I set up.

I'm at a loss for what to do now. Could it be a bios setting or 
something? What makes you so sure that the hardware isn't at fault?
