Same problem on Debian jessie (Linux olympus 3.13-1-amd64 #1 SMP Debian 3.13.10-1 (2014-04-15) x86_64 GNU/Linux),
steam 1.0.0.47-2,
fglrx-driver 1:14.4-2,
HD7970 (3 connected displays)
Installed and updated just fine, but does not start.
Output when starting it in console: http://pastebin.com/TrnYePGP
Output when starting it in console with STEAM_RUNTIME=0: http://pastebin.com/v03ciMk1
EDIT: I am able to start Steam with the open-source driver, but as soon as I revert to the proprietary one, it stops working again. Performance-wise, the open-source driver just isn't suited for gaming on this card, so someone should definitely look into this.
Installing libxinerama1:i386 (with fglrx) steam install and run without problems.
Nothing extracted yet.

I know that the installation works on the open drivers.
