You can run two maps, you just have to program the two different parts of the chip.

I just checked how the code sits in a bin file on my hex editor...it pretty much starts at 0000 and ends at 7220 for a boost bin. After that all that's left is from 7220 to 7ff0 for code space...not enough for another map. I'm pretty sure the 256's are limited to 32kb, and the 512's can do 64kb.
