cardbus: limit IO windows to 256 bytes
That's what we've always historically done, and bigger windows seem to confuse some cardbus bridges. Or something. Alan reports that this makes the ThinkPad 600x series work properly again: the 4kB IO window for some reason made IDE DMA not work, which makes IDE painfully slow even if it works after DMA timeouts.
