I guess this question is better suited for a mailing list covering iMON.

LCDd used any device configured the appropriate driver section in LCDd.conf.

Here a few hints what I would do:
- Check whether /dev/lcd0  is a device file or a symbolic link on the 
  Gentoo box.
- Check whether the the device file or the symlink gets dynamically 
  created on loading of the module / deleted upon deletion of the module
  on the Gentoo box.
- Either create the device file (in case the device file is not created
  dynamically) / symlink (in case it is a static symlink)
- Or look where the dynamic configuration is done in Gentoo and copying that.
  (I'd look around modbrobe / udev or something like that)


Using neither Gentoo, nor Spblinux nor iMON this is all the help that I can 
give.

If you found out, what the problem what  maybe you can add a little chapter 
about troubleshooting for the imon chapter of the LCdproc User Guide.

Peter
