"FirePro 2260" leads me to believe it's a 2000 series card. Having the
Vendor:Device ID pairing would help clarify, but looking at the pci id's
database I'm guessing it's either 1002:95ce or 1002:95cf.

You have a number of choices:
1. Use the v13.1 legacy driver from AMD and downgrade xorg\* to the last
release that came with RHEL 6.3 and exclude future updates. If you wish
to use the elrepo package it's called kmod-fglrx-legacy /
fglrx-legacy-x11-drv (currently version 13.1-2) and is currently in the
testing repo. Obviously downgrading xorg packages has potential security
implications.
2. Uninstall the AMD proprietary drivers and use the distro kernel driver.
3. Ask AMD when they will update the legacy driver to support Xorg ABI 13.
4. Buy a new (supported) card.
A fifth option is to use el5 which uses an older supported version of
Xorg (I do find it kind of ironic that RHEL6 ships with such a new
version of Xorg that some proprietary drivers don't support it - more
the kind of thing you expect to run into on Ubuntu or Fedora than
Enterprise Linux).
