Да, работает:

$ cat /etc/X11/xorg.conf.d/10-nvidia.conf
Section "OutputClass"
	Identifier "nvidia"
	MatchDriver "nvidia-drm"
	Driver "nvidia"
	Option "AllowEmptyInitialConfiguration"
	Option "PrimaryGPU" "yes"
	Option "ConnectToAcpid" "0"
	ModulePath "/usr/lib64/X11/nvidia"
EndSection

Патченный xorg лежит тут - http://git.altlinux.org/people/lakostis/packages/?p=xorg-server.git;a=shortlog;h=refs/heads/server-1.19/glvnd

Также могу пересобрать livecd чтобы проверить работу с несколькими GPU.
