Package: fglrx-driver
Version: 1:12-6+point-3
Severity: normal
Tags: patch
Currently the radeon module is unconditionally blacklisted if the
fglrx-driver package is installed. The attached patch changes the
blacklist to an install script wich only prevents radeon from being
loaded if the system actually contains a card that is also supported by
the fglrx kernel module.
This is usefull for Debian Live systems where the hardware present may
change between reboots quite frequently and you don't want to uninstall
the fglrx-driver because of that.
