presumably the ROM api is largely fixed, as is the address where it lives.  so 
create a header file that declares const function pointers with a fixed 
address.  then all your C code will simply call that address directly.

if your ROM doesnt have any sort of stable abi, i imagine you could write a 
script that converts the final linked addresses into a C header file.
