How do I install to a different drive? Steam won't allow it.

[HFC_Dolphin]

There is a specific problem that can't be solved by changing the whole STEAM installation/folders to a new drive.
Let me explain.

I bought a new pc and I got an expensive SSD disk to be used ONLY for Win7, drivers and Clod. It's only 64GB and it can't fit all my STEAM games in there.
I don't care if X-steam game is installed in D drive, but all I want to do is to have CLOD in the SSD drive.

Anyone knows how to do this?
Silly Steam, they should be more smart and have a solution to this specific problem.

Anyone who can help?
