You are correct.  Video professionals are doing this right now.  The 
TARGA and ATVista boards will work in the Amiga PC slots.  You will have
to have a BridgeBoard to access these frame buffers.  PC software for 
these cards will run on the BridgeBoard and access the cards.  Active 
Circuits has programs to allow you to convert images to use them on these 
cards and even to allow Amiga software to render to these boards in real 
time.  Roman Ormandee, the author of Caligari, has a demo tape of Caligari
that was done this way.
