Always allocate RAM and ROM areas at the same time. This avoids having ROM
suddenly allocated below RAM and thus not working. Besides, this may fix a latent deallocation bug in real addressing mode (i.e. release the whole block allocated at once, not separately). Side effect: this makes Basilisk II work in direct addressing mode with JIT on Darwin 8.0.1 for x86.
