I'm not asking 'should I...'

Is it possible, given the increasing video ram being slapped in video
cards these days to utilize unused vram as system ram? For instance,
if you're running in 80x24 text, and have a 16M or 32M board, to be
able to hijack the memory for another lump of memory? Or maybe use it
as 'fast swap'?

This is more of a curiosity question that an actual desire to *do*
it.
