ATI Eyefinity and one big desktop

[glerosbe]

Hello

I'm kind of a Linux Mint/Cinnamon newbe, I realy want my Cinnamon desktop to work in the same way that my Windows 7 desktop, when using ATI Eyefinity with 3 monitors, including span the bottom panel over all 3 monitors.

Is this possible on Linux Mint 14 with Cinnamon?

And yes, I know I ask this as a "Windows user", but this one of the few things, that make me still use Windows 7...
