Well, my mistake in stating OF stdout. Rather -

- KDB used console->write() rather than udbg_write() to print data.
  The patch changes _just_ that (makes it similar to xmon).
- Reading in data has always been through ppc_md.udbg_getc_poll()
  which should take care of the stdin problem. (Pls correct me if
  I am wrong! :))
