I'm in suspense now.  Did you report this upstream?

If not:

 - do you still have access to this hardware, and if so are you
   still interested in pursuing this?  ("No" is fine, but please do
   let us know so we can act accordingly.)

 - how do current squeeze kernels behave?

 - how about current 3.x.y kernels from wheezy or sid?  (The only
   packages from outside squeeze that should be needed in order to
   test this on squeeze are the kernel image itself, linux-base,
   and initramfs-tools.)

 - if squeeze kernels do not reproduce the problem, we can declare
   victory.  Yay!

   if squeeze kernels reproduce the problem but 3.x.y does not,
   it would be useful to try a few kernels halfway between to narrow
   down the range to search for a fix.  Historic precompiled kernels
   can be found at <http://snapshot.debian.org/package/linux-2.6>.

   if 3.x.y kernels reproduce the problem, please report this upstream
   and let us know the bug number so we can track it.

Hope that helps and sorry for the trouble,
Jonathan
