I guess we disabled some options when we built our kernels to allow a
simple command line. However, I don't know which ones.

I wasn't aware that such a command exists. However, the --run option
seems to call the script "runimage". You might want to take a look at
the options being set or maybe simply retrieve the qemu command line
created by it (if that's not how you created your first command line).

Sorry to not be more helpful.
