You can put 256 in both the upper and the lower slots, but the reality is that some machines read the entire amount of 256 MB in teh lower slot and some do not; they read only 128MB of that even though there is a 256MB stick in the slot. So you can put in 512, but you may get either 512 or 384MB, depending on the whim of that particular machine.
Yes, the Rev A and B are listed as having 256MB as max memory because the single 256MB sticks (making the max of 512MB) were unavailable at the time those machines were the top of the home consumer line. 256 max, or two 128 sticks, was the highest available memory for them at that time.
