Well, it sounds like it was a bug to me. ;-)

Now I'm curious: are you still using this hardware?  If so, what kernel
do you use these days, and how does it act?

If the problem is still present in current squeeze kernels, it would
be useful to find a fix and backport it.  If the problem is still
present in 3.5 from experimental, we should take this upstream.

Thanks and hope that helps,
Jonathan
