I don't know if that would 'solve' the problem, but one major difference from qemu is that a jailed host runs the same kernel with the master. This means that i386 programs do not run in 'native' i386 mode, but in emulated mode. The FreeBSD kernel already includes support for running i386 programs in emulated mode, but since I haven't done this I am not sure how feasible or useful it is.
