There's no single thing that makes them hard.  It's a bunch of little 
things that get compounded:

- how/where to allocate the memory
- updating the drivers to allow rendering to that memory, rather
   than the front/back color buffers.
- implementing all the infrastructure
- implementing the programming API
- etc.

It's a real mess.
