    While being a "nvidia-guy" myself (long before ATI was bought by
    AMD), out of curiosity, I've asked myself "what would I do" and
    looked into AMD driver support in Debian.
    And to my surprise, I didn't found a simple way like "amd-driver"
    meta-package to install, as opposed to "nvidia-driver" package for
    nvidia-based VGAs.
    So, if I were you, I would bite the bullet and use latest official
    driver [1] provided by AMD, simply because there are no other
    options.
    Upon further examination "*.deb" packages they provide will be
    installed into paths with "*/opt/*" and because of that, they won't
    overwrite any Debian-native files, so there is little to none
    possibility to create "franken-debian" by installing them. And since
    they are packaged into ".deb" files you can always cleanly uninstall
    them.
    The only thing I would do prior to driver installation is to enable
    i386 architecture support [2] on my system, if it wasn't enabled
    already:
        # dpkg --add-architecture i386
      
    I wonder why a convenient "amd-driver" meta-package wasn't
    created yet...
