mpc8260: ncurses -> keypad() failing.

Hi,
We have developed a BRouter and use ncurses for some CUI stuff, like
configuring our router on a custom designed board (ppc 8260) running
eldk linux, kernel is different :-)

When I issue the call keypad(), it returns failure (ERR).
I don't know what the error is. it does not set errno, so I cannot use
perror().
My terminal type is set to
$ export TERM=vt100
$ export TERMINFO=/usr/share/terminfo

I have made sure that /usr/share/terminfo contains v directory and vt100
  files.The same code works in RH 7.2 on i386, where we tested the
functionality.

Any idea/suggestion ?
Thanks for your time.
Om.
