Implemeting the hardcoded memory addresses is not as hard as it
sounds. All the hardcoded addresses (at least the ones implemented by
bochs) are in the last 8K of the bios. So, you just need to make sure
the C code fits in the first 54K. A simple assembler file can then
put trampolines at the fixed addresses.
As Jun points out, I've already done this.
