Well, you are on your own on this one and is not a big deal to 
point the Bt848 to your physical display buffer. The requirement for
the graphics is is that it presents a linear frame buffer and
that is mapped in . Other considerations such as RGB vs BGR can be handled 
by the Bt848. If push comes to shove I would just dump the Hercules card
and get one that can do the job.

Assuming worst case scenario, that you can't directly dump video to your
display buffer. You can still use the Bt848 to capture video and
display it using "tv" which uses X to load an image to the card 
using the shared memory extensions in the X server. Please note
that shared memory is for inter process communcation and is
not necessarily for inter-device communication.
