X keyboard input focus on N900

When I run emacs23-lucid on an N900, I can't get the emacs window to get
keyboard input focus. This happens two different ways:

- running emacs23-lucid in a Debian sid chroot
- running a remote emacs23-lucid on Debian lenny via ssh in maemo5

Any ideas on how to fix this? (I do both of these under maemo4 on an N810
without problem.)

Thanks,
