FWIW, I've added mappings for a near full disassembly of the CTP drivers, and a mostly complete disassembly of the DSP driver.
duodsp4.dsk
Nothing popped out at me while disassembling, but I haven't followed it closely. I mostly just set up the mappings.
From the Duo System devnote, it's probably somewhere in the $5000 0000 - $5FFF FFFF range, since that's dedicated to IO devices.
