Memory info (GL_NVX_gpu_memory_info):

...What does "available dedicated video memory" mean?

I don't know what "Currently available dedicated video memory" means, but you should look at "Video memory" and "Dedicated video memory".
Other ways to check (but may fail):

It's interesting that "Dedicated video memory" and "Total available memory" are the same (nouveau driver have second value much higher).
This interesting thread is about that:

Dedicated Video Memory or VRAM is the fixed amount of memory installed on your graphics card.
