Brendan, SDCC does not accept a linker script, but it creates one (extension .lnk) when calling the linker. You can adapt it (or write it yourself) and then call the linker manually instead of through SDCC. Use sdcc -V --verbose to see how the linker is called.
To relocate only the code and not the vectors, you could use a .asm file with the vectors in an ABS area with .org 0x0000. You could also try to use -Wl-bCSEG=0x1000 and the like.
