Log Message:
Reworked the packaging of the AMD/ATI proprietary drivers to specify
both stable and unstable releases.  The unstable driver can now
coexist with the stable driver, and will not be picked up by default.

ati-xfree86-bin: Reverted from 8.40.4 to 8.38.6: 8.40.4 is unstable
    and can cause machine lockups and shouldn't be the default.

ati-xfree86-bin-init: removed, and merged initati functionality into
    ati-xfree86-bin-unstable

ati-xfree86-bin-unstable: This packages the 8.40.4 driver.  This package
    provides initiati, which uses the stable driver to initialize the card
    and thus depends on ati-xfree86-bin.
