Yeah, I double-checked: the IO alignment is 4 bytes, the MEM alignment is
4k.

So if we had a separate alignment word we could use that, but in the
meantime I think IORESOURCE_SIZEALIGN is good enough, and a bit more
readable than the STARTALIGN thing.

Now we just need to have somebody test it. It turns out that I no longer
have any Cardbus cards, since my laptops now all have built-in wireless.
Boo hiss for me.
