^^^^Please go back and reread my post, especially the last sentence. If I am not clear, I apologize.

I understand your last sentence, that's why I asked. That particular sentence about "flash card can work with Apple driver" doesn't match to what I know. As I said. And as your last sentence stated. The new card must work with web driver.
And for older card, they can work with Apple driver regardless flashed or not. And I cannot think a single card that will work with Apple driver if flashed, and cannot work with Apple driver if unflashed. That's why I ask.
I totally understand that you are trying to help the others by sharing your experience. So do I. I just want to make things clear, and make sure the others won't go to flash the card because they believe only flashed card can run with Apple driver.
@Filin , You can boot into 10.4 Tiger with flashed R9 280X (i did), but it doesn't work with Apple drivers, it is just EFI initializing the screen. It is good enough to get some things done (for example - installing web drivers
).
That's my understanding as well, it's drives by the EFI, but not Apple driver.
I am just a beginner in this area. I really have no idea how this MVC EFI work. As I can think of, there can be 3 cases. (All assume MVC flashed and no web driver yet)
1) EFI work at boot. And no Apple driver avail for that card. So, the display is coming from the EFI.
2) EFI work at boot, and able to confuse MacOS that is another card, which allow the OS provide other driver for this particular card to work. Well below the optimum performance, and may be buggy, but the screen is actually driven by the driver at some stage.
3) EFI work at boot, and native Apple driver available to this card. In the case, the driver will take over at some stage during boot.
So, my understanding is for both Maxwell and Pascal card. They belongs to case 1.
For other card, they belongs to case 3.
And no card belongs to case 2.
