As a work around to these problems I tend to run the games in windowed mode at my native resolution and hide the window border. It causes far less problems then trying to run games full screen on a dual monitor.
This is not the only game that has this sort of issue. I noticed both Penumbra: Overture and Killing Floor both disabled my second monitor when I launched them on my primary.
However, in my case, that monitor comes back when I exit the game. I've not tried running them in Windowed mode yet.
I've noticed that with Trine 2, TF2, and Waveform won't restore the secondary monitor when they are closed either.
Based on past experience, fullscreen games on Linux almost always disable the secondary monitor in a xinerama/twinview setup. Although they always re-enable it when they quit.
Don't mind it disabling the other monitor(s) while gaming, but i'd like it/them back afterward. Incidentally, i was able to restore the other monitor immediately from Catalyst without restarting my X session.
You can also use xrandr. You just need to know the full combined resolution of all your monitors. Just open up a terminal and type xrandr -s 3360x1050, substituting the appropriate resolution.
grumble.. it's because I shipped SDL 1.2.14 which has XrandR enabled by default (which has that annoying issue). I'll upgrade it to 1.2.15 which disabled it's use of XrandR and won't have this issue. (this most likely is the same cause for the other games mentioned here)
This should no longer happen with the latest update.
Latest update of what; Steam or something else?

Sorry, of uplink. I bumped the SDL version which should fix the fullscreen issues.
Uplink starts fine, looks fine, and runs fine, but when I exit the game, the monitor not used by the game has been completely disabled. My Plasma taskbar has moved to the now-active monitor, but all other widgets are missing. Logs from the game's run appear to show some sort of X error:
