Problems starting /init

I have a kernel for a new board (Linux 188.8.131.52, Pico E12/Xilinx V4
PPC405) booting to the point of starting /init.
/init appears to be getting loaded correctly - the execve call seems
happy. But I get no output on the console.
I have tried:
inside init/main.c immediately before starting /init - works fine.
starting a "hello World" application written in PPC asm as /init -
works fine. The kernel panics on exit but that is normal, /init is not
supposed to exit.
starting a c "Hello World" application that uses glibc, fputs, printf,
fwrite, to display a string - again works fine.
But I can not get busybox to output a thing either run as /init or run
I have aslo tried /bin/sash - no output.
I have even cross compiled sash - with all kinds of "I am here"
debugging scattered through main(), If I runn it on a powerbook, I get
what I expect. If I run it as /bin/sh on the e12 I get no output.
Does anyone even have any ideas what I can look at ?
