busybox tries to open the console device and does fairly extensive surgery with the stdio descriptors. So your apps that assume fds 0,1,2 to be stdin/stdout/stderr are functioning fine, but busybox is probably choking because it's opening/configuring the console devices. I've worked through this with someone before when we wanted busybox to just run with the existing fds - we eventually beat it into submission but then ended up changing/replacing the console driver instead and going back to vanilla busybox. If you take a look through the busybox source, you should find the various fork/dup/ctrl/exit gymnastics and with a little patience, you might be able to hack around it. But it might be easier in the long run to figure out where the opening/manipulation of /dev/console (or whatever it's opening) is going wrong. Sorry I can't help you further. Good luck.
