Ick.  This isn't ok, we can't take patches for staging stuff in files
outside of drivers/staging/

So for now, I've deleted the drivers/staging/dream/ directory from my
tree, which will get pushed for 2.6.33.  Please clean the code up and
get it into buildable shape and I will be glad to add the drivers back
into the staging directory at that time.
