I wonder if that requirement depends on which card it is? I see comments in the thread that it needs disabling with the legacy driver, I thought mine was one of the legacy drivers.

It'd be easier if they had one package, and it's installing routines picked the right driver from its contents for the job. I noticed, too, that the different packages (for other cards) had different contents in other ways (i.e. some documentation versus none). -- [tim@bigblack ~]$ rm -rfd /*^H^H^H^H^H^H^H^H^H^Huname -ipr 2.6.21-1.3228.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5.
