Sorry for the long quiet.  Do you still have access to this system?
Can you reproduce the bug with current squeeze kernels?  (No
particular relevant change I can think of; just would like to know
before hunting for a patch to apply.)

If you can still reproduce it, please attach full "dmesg" output from
booting and reproducing the problem on an affected kernel and from
booting an unaffected kernel.

Thanks,
Jonathan
