As a workaround I now use kernel-rt with the FLOSS nv driver, so for 3D
acceleration I need to boot kernel-ARCH. 

# pacman -Syu xf86-video-nv

# grep DAEMONS= /etc/rc.conf
  DAEMONS=(69switch_xorg.conf hwclock syslog-ng !network !netfs crond
  acpid dbus)

# cat /etc/rc.d/69switch_xorg.conf
  #! /bin/sh
  # /etc/rcS.d/Switch_xorg_conf

  rm /etc/X11/xorg.conf
  case $(uname -r) in
      *rt*)
          cp /etc/X11/xorg.conf.nv /etc/X11/xorg.conf
          ;;
      *)
	  cp /etc/X11/xorg.conf.nvidia /etc/X11/xorg.conf
          ;;
  esac

# grep nv /etc/X11/xorg.conf.nv
        #Driver	    "nvidia"
	Driver	    "nv"

# grep nv /etc/X11/xorg.conf.nvidia
        Driver	    "nvidia"
	#Driver	    "nv"
