Allow physical-memory allocations within stolen memory.
Because stolen memory happens to be a contiguous block of high system memory, we can just read the GTT entries for it to get physical addresses for our allocations there if needed. This reduces fragmentation of the aperture space, and will often reclaim up to 7 MB of memory that had been left unused since the simplified aperture manager was put in place, but without reintroducing the complexities of the old aperture manager.
