Downgrade 2011 iMac per loaded with mountain lion back to lion or snow leopard?

Can it be done?

Find it here (two specs of 2011 iMacs exist). Oldest version you can install is pre-installed Mac OSX.

That sounds likely: if a machine has only ever shipped with ML then any previous OS won't have platform drivers for that machine and won't be able to boot.
