Gregor is right- 
a -T9 should do the trick (in the latest CVS version).

The corresponding AVM enabling code is to be found at lib/rfxswf.c at
line 1314:

  if(swf->fileVersion >= 9) {
      if (swf->firstTag && swf->firstTag->id != ST_FILEATTRIBUTES)
      {
          U32 flags = 0x8; // | 128 = usenetwork, | 8 = hasmetadata
          swf_SetU32(swf_InsertTagBefore(swf, 
swf->firstTag,ST_FILEATTRIBUTES),flags);
      }
  }

1992? Not bad. You beat me by 4 years :)

Always! 

Of course, it depends on what you would like to help me with.

The most pressing thing right now are natural gradients, i.e. the
conversion of PDF gradients to SWF gradients. Right now, PDF gradients
are converted to (thousands of) SWF polygons, even though SWF has a
gradient command. 
In order to implement this, the gradient call in lib/devices/swf.c needs
to be implemented, and lib/pdf/GFXOutputDev.cc needs to be tweaked os it
passes gradients (shaded fills) through.
