Somewhat related, I do actually have a patch to change the usage hint
for static vertex buffers to GL_STATIC_DRAW_ARB in my tree, which
should actually make the driver more likely to initially place those
in VRAM instead of GTT. (It mostly just helps with initial fps after a
VB is just created, most drivers eventually figure out the optimal
placement anyway and migrate the buffer to vram.)
