The PCI standard allows for up to 256 buses, each with up to 32 slots, and each slot can have up to 8 functions. PCIe devices have a full 4096 bytes worth of configuration registers. Multiply all that and you get 256MB. Also, keep in mind that it's not allocating 256MB of memory; it's allocating 256MB of address space and memory-mapping the configuration registers in that space.
