That's how PCI sizing works: you write all ones to the register, and read back the result. The low bits won't change, and that indicates the size. But if _none_ of the bits change, then that simply means that the size will be calculated to be 0xffffffff-start. So the sizing will "work", it will just always report that the BAR covers everything from start to the 4G limit.
