KMS -- do we have to do anything at all to enable it?
The KMS sections says it's on by default, should we even have to put radeon in MODULES any longer? If not, the intro to that section should probably mention that "you can skip the rest of this section if 'dmesg|grep modesetting' shows 'radeon kernel modesetting enabled'.
I don't know how others feel about this, but my preferred setup is to put options radeon modeset=1 in modprobe.conf and then to include modprobe.con along with the radeon module in mkinitcpio.conf. This way KMS is enabled once for both early and late start. Also, in the event of problems, radeon.modeset=1 can still be added as a kernel option to the bootloader. --piezoelectric
