This has been fixed in recent kernels. See

I can imagine two workarounds:
- either keep you current Squeeze kernel and downgrade udev (and
related packages) to the previous version (that did not require
kernel's accept4 syscall)
- or keep your current udev and upgrade to a newer kernel (backported
from Wheezy if necessary) that implement accept4 syscall.

In both scenarii, you probably need to perform the downgrade/upgrade
from a chroot environment.

On my side, I originally installed Wheezy months (years?) ago using
debootstrap from a working minimal Squeeze installation (pre-udev
issue however) on a separate HDD.

Perhaps can you follow the same (long) route?
