Did you remember to plug the daughter board back in before testing?  A Denise chip from an Amiga 2000 should also work.  Afterall, the Amiga 3000 is nothing more then an Amiga 2000 with the A2091, A2320 Amber, and the Commodore 68030 boards built in.

With a Commodore A3630 board installed, an Amiga 2000 becomes a 32-bit machine.  Also, keep in mind, there is really not that much difference between 24-bit (Amiga 2000) and 32-bit (Amiga 3000).  In fact, did you know that an Amiga 2000 with an 030 board installed actually runs faster then an Amiga 3000 with an 030?

There are 2 versions of the Super Denise chip, r3 and r4.
 
An Amiga 2000 with an 030/25 is faster then an Amiga 3000 with an 030/25.
 
Now, graphics is a different story.  They tend to be slightly faster on the Zorro III bus.

WRONG! Do your homework, I have.
 
The Amiga 2000's bus is 24 bits wide, not 16 bits (I can not remember where I read this, but it stuck in my brain because I thaught it was odd).
 
The reason why an Amiga 2000 will usually be faster then and Amiga 3000 or 4000, both using the same processor, is because the Amiga 2000 does not have a Super Buster chip, which is a bottle-neck on the Amiga 3000 and 4000 machines.
 
This fact is actually printed in the Video Toaster manual.
