We already have graphics cards with 2 GB RAM, so anything above 2 GB is unreachable during sizing. For a graphics card with 4 GB RAM, every single freaking 32bit location will be inaccessible. That means it it totally irrelevant whether you unshare or not, the machine will simply fail.
The framebuffer size or location doesn't matter. The vbios is running in real mode so it can't access that memory either. The issue is that the framebuffer sizing by the vbios causes the subtractive decode path to be rerouted and the code can no longer be fetched.
