This API sucks. Fortunately it's mostly unused at this point. geode, sis, and xgi need minor patches to use the corresponding pciaccess code, neomagic will (more explicitly) lose its non-PCI support, and newport will need to be ported to /dev/mem or the platform bus or something.
This should also make it pretty clear that alpha's sparse memory support was basically not a thing anymore, very few tears shed.
