No Umlauts on console with Kernel 2.6.26

[Til Schubbe <lists@lists.schubbe.org>]

Hi,

I upgraded a Lenny from Kernel 2.6.18-6-486 to 2.6.26-2-486.
Booting with 2.6.26 I dont get any characters displayed by
pressing German umlaut-keys on the console. X works fine.

So I did a
# dpkg-reconfigure console-data
and set it to 'pc qwertz German latin1 - no dead keys'. Now
pushing an umlaut-key generates 2 characters. First a capital 'A',
and then a special character. But I don't get German umlauts.

Umlauts still work when I reboot with Kernel 2.6.18.

Do I have to add something to /etc/console, boottime* etc.?

What else do I have to do to get my umlauts back with 2.6.26?

TIA
Til
