...and I've just submitted the following two patches upstream which implement this:

http://patchwork.ozlabs.org/patch/87807/
http://patchwork.ozlabs.org/patch/87806/

so passing '-M versatilepb -m 512' to qemu-system-arm results in it failing cleanly with the message:
qemu: maximum permitted RAM size for 'versatilepb' is 256M
