We don't need a VGA core.
The primary markets for this card are going to be developers who don't care about using a standard VGA card for pre-kernel-loaded stuff, the embedded and server markets, where they can simply write a new system BIOS that emulates 80x25 text mode on the framebuffer, and the multi-head market, where the kernel or X will be responsible for the extra heads anyway.
Once the kernel or X has taken over the framebuffer, there is certainly no need for a VGA core.
As far as I am concerned, the first version of this card is going to be more or less an expensive proof-of-concept thing. It _will_ cost more than a brand new off-the-shelf VGA card, and it _will_ cost more than a second-hand VGA card with documented registers. That doesn't mean it isn't worth doing, though.
