Comment 4 for bug 12629

I hacked kbd and console-tools packages in Debian so that keymaps
work the same when keyboard is in ASCII and UTF-8 modes, and thus
there is no reason to have these duplicated keymaps.
Last day I checked on my Debian box (with kbd, not console-tools):
  $ export LANG=en_US.UTF-8
  $ unicode_start
  $ loadkeys pl1
and AltGr+e printed eogonek as expected. It should be similar with
Debian console-tools (but I did not test it); so if you have trouble,
some patch may get lost in Ubuntu console-tools. Do the commands
above let you enter an eogonek with AltGr+e?
There are still some issues when generating boottime.kmap.gz, but
AFAICT your keymap would not solve them.
