case sensitive collation does not seem to work in 5.5

Hi all experts out there.

Under realease 5.0.66 we had created a new case sensitive collation latin1_german1_cs.
Everything worked well.
Key values like 'abc' and 'Abc' where stored in different rows.
Lately, we moved from 5.0.66 to 5.5.
Now our collation doesn't work anymore.
Storing a row with key 'Abc' while key 'abc' already exists yields 'Dupkey'.

Any idea?

p.s.
I installed the latest Release 5.5.14.
Changed collation id in Index.xml to 1024, which is recommended for user-defined collations.
Now it works, but only for MyISAM.
With InnoDB, even the creation of a table with columns of collation 'latin1_german1_cs' yields an error.

The CREATE statement:
USE test2;
CREATE TABLE `tabelle1` (
`feld1` char(30) COLLATE latin1_german1_cs NOT NULL,
`feld2` varchar(255) COLLATE latin1_german1_cs NOT NULL,
PRIMARY KEY (`feld1`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_german1_cs;

The Message:
ERROR 1005 (HY000): Can't create table 'test2.tabelle1' (errno: 1005)
