One thing you could do, if this is an A1200 only upgrade, is use a technique similar to the one used in the Blizzard PPC.
Use the onboard EC020 to boot make the patches, load the libraries and then pass over to the Coldfire.
Dunno if you can do that with the TrapDoor interface, I think it's either the CPU on the motherboard, or ones on the card. (I suppose they could slap down an uber cheap EC020 on the Dragonboard?)
