Yes, it's the size of the frame buffer in physical address space than 
I'm after.  For other display adapters, I recognize which particular 
memory BAR is holding the (physical) address of the (main) frame buffer 
by looking at the size requirement.  Some display adapters provide 
multiple windows onto the VRAM of different sizes and characteristics, 
and they are distinguishable by size.  Some, indeed, provide memory 
resources for things other than frame buffers.  Of course, this fake 
display adapter is just providing the one memory BAR; so I could just 
chop out the size checks and simply take the first (and presumably only) 
memory resource for the device to always be the frame buffer.

In fact, I shall do that for now.
