My bad...

service_harddrake has path checking hardcoded so when I moved install path for built fglrx module to match current kernel layout, service_harddrake rewrites xorg.conf before display_driver_helper runs so it switches to the free driver


Fixed in fglrx-13.250.18-4.mga4 + kmod-13.250.18.mga4


The same applies to the nvidia drivers , so I'll fix them too.

We can document how to workaround it in the errata, but it is annoying that it
was working previously, and isn't now.

Oops. Wrong bug. Sorry.
