Okay, I rendered it. It is just that the black area lies in shadow and 
therefore is black. There are various ways to avoid the problem. The 
easiest is probably to use 'ambient' in the finish.

So use
  finish{diffuse 0.3 ambient .7}
for the text's finish. Try some different combination for the two values.

Other possibilities would be:
- change the lighting, so that the cut out is everywhere lit (several light 
sources, aera light)
- make the cutting out less deep
- use radiosity
