hey Martin,
 Thanks for your detailed investigation.
Can you reproduce with the latest trunk builds? I didn't see any
changesets upstream that obviously fix this issue, but just in case...

Trunk builds can be installed from here:
 deb http://kernel-archive.buildserver.net/debian-kernel trunk main

If you can still reproduce, we should file it upstream
(http://bugzilla.kernel.org).
