This one nukes all framebuffers, which is a bit much. In reality gma500 is igpu and never shipped with anything discrete, so there should not be any difference. v2: Unfortunately the framebuffer sits outside of the pci bars for gma500, and so only using the pci helpers won't be enough. Otoh if we only use non-pci helper, then we don't get the vga handling, and subsequent refactoring to untangle these special cases won't work. It's not pretty, but the simplest fix (since gma500 really is the only quirky pci driver like this we have) is to just have both calls.

This simply isn't it. If you have to work around your own API, it's time to rethink the API.
