Yes, this is interesting.  Can you still reproduce it?

If so, the next useful step would be to try a 3.x kernel from sid
or experimental.  (The only packages aside from linux-image-<version>
from outside squeeze that should be needed in order to do so are
linux-base and initramfs-tools.)  Then:

 - if it is broken, please report this upstream to
   http://bugs.freedesktop.org/ following instructions from [1],
   and let us know the bug number so we can track it

 - if it is fixed (and if still broken in the latest squeeze kernel),
   please try a version halfway between from [2] to narrow down the
   range of versions where we should search for a fix.

Thanks much, and sorry for the long silence.
Jonathan
