Work on the feature request (https://sourceforge.net/p/sdcc/feature-requests/556/) has been progressing well. You can try it using current source (revision 10340 or newer). To enable support for the 24-bit space, use --model-large. Since you have previous experience with modifying SDCC for this, your comments (and possibly patches) would certainly be helpful.
