If the application is writing directly to the hardware - as may be the case 
- - then there isn't any straightforward solution (and certainly not one 
using x0rfbserver).

I think, although I am not sure, that standard screen snapshot tools wont' 
be able to capture this either. Try using a snapshot tool, such as the 
basic 'xwd' (xwd -root > file) to get a screen snapshot at the console; if 
the application's "x-ray" image (viewport) is blank, then it's going 
directly to the hardware.

If, on the other hand, it's simply taking advantage of the Creator3D's 
ability to display both 8 and 24 bit visuals, then it may be possible to 
make it work. However, it may be tricky; if I have time, I can look at it 
here (we have multiple Solaris systems with Creator cards).
