In general I'm happy to take patches for Haiku.  But I wouldn't want
to see #ifdef __HAIKU__ lines scattered all over the code.  Hopefully,
that can be limited to header files as with other platforms.

What GPUs/cards do you need to support?  Does this involve restoring
any legacy drivers that were removed a few weeks ago?  Could you move
to Gallium-based drivers?
