Thanks, Eric.  Unfortunately I don't have the hardware.

Gerd, would you be able to try this patch?  It works like this:

  apt-get install git build-essential
  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
  cd linux
  ... apply the fix, for example using "patch -p1" ...
  make localmodconfig; # minimal configuration
  make deb-pkg
  dpkg -i ../<name of package>
  reboot

Feel free to email me privately if you have any questions.

Regards,
Jonathan
