    Being fed up with the constant freezes in Lion and seeing that no help wil come, I thought that a downgrade to SL is in order. How can I do this the least painful way? First backup the machine with Time Machine, then install SL and restore with TM again? Will that give any problems I should be aware of?

    Is the new iMac even compatible with SL as it has Lion factory-installed?

    You will need a SL disk with at least version 10.6.7 (I believe) to support the Sandy Bridge processors in the 2011 iMac.

    Also not sure if you can use a Lion TM backup with SL,

    No. It supported Sandy Bridge CPU's but not the new AMD Radeon Cards. DO NOT DOWNGRADE, you will have many problems running it..

    The 2011 iMac's came out in march/april, Lion was released in July? SL is compatible with the 2011 iMac's and MBP's, just not the 2011 MBA's and Mini's.

    Have you contacted Apple support about the issues you are having with your new iMac. My 2011 iMac came pre-installed with SL. I did a clean install of Lion and have had no freezes or lockups so I suspect that maybe something else is causing the issue.

    I still cant fathom why people call going to lion to snow leopard a downgrade. if your getting more features, more stability and better usability its an upgrade yes?

    I always refer going from Lion to SL as an UPGRADE.

    Imac 2011 came out in May with 10.6.6 DVD. So this mean any install with 10.6.6 or above will work.
