Hmm, just a random shot (shouldn't be the case, but just to be on the safe side) -- could you please try echo 0 > /proc/sys/kernel/randomize_va_space to see whether it removes the segfault by any chance? I don't know how exactly execution of real-mode code through libx86 works, but this might be worth trying before starting the next round of bisection.
