I've seen numerous reports, and the conclusion is ...
  Don't!  They are disabled for a reason!

Remember, GPUs are now _huge_ in transitor count.  It's much
like fabbing CPUs these days, you have defects in the layers.

On CPUs, sometimes you can localize those defects to a cache
block (which is the majority of a CPU), and sell the CPU in a
model with less cache.  

Same deal on GPUs, various vector/pipes are damaged, so the
turn off a block of 4 or 8 and sell it as a different
product.  If you enable some, you might be enabling yourself
a faulty product.
