The only accelerated PPC's around at the moment are the Dell Axim X50/51v or Ipaq 4700's with VGA screens. It sounds like you'll have enough grunt to try it out with some chance of success, though.
[Edit] Actually, I should qualify by saying that those are the devices I'm aware of at the moment. There are other VGA devices about (like the Toshiba) but I don't know if they have a hardware accelerator on board.
