I feared something like that. You do not know by chance if glTexSubImage
might be zero copy if the part copied is the full size? I know that's
how the binary ATI drivers behave (for PBOs that is - their PBO
implementation must be close to the buggiest piece of code on earth).
I tested glTexImage with the older Intel drivers and it did not change
performance one bit.

Mine is now:

server glx version string: 1.2
client glx version string: 1.4
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_MESA_allocate_memory, 
GLX version: 1.2
OpenGL version string: 1.4 Mesa 7.2

The part after "GLX version: 1.2" previously had a
GLX_MESA_allocate_memory, too that since the update disappeared.
