I'm afraid that with Squeeze being old-old-stable at this point your
best bet is going to be to upgrade at least the kernel if not the whole
distro to something > Squeeze.
I'd suggest starting with 2.6.32-48squeeze14 from the lts effort, if
that doesn't help (which I think is most likely going to be the case)
then 3.2.68-1+deb7u3~bpo60+1 from the o-o-bpo might be a good bet.
That's assuming you cannot upgrade the entire system to Wheezy or even
Jessie, which would be best of course.
