Euhm, I can remove xorg-drivers without any dependencies, but not a
xorg-x11-drv-* package. I'm not sure why these other packages depend on
xorg-drivers, but that's not how a meta package would be used:
yum install @foo would install bar and baz
yum remove baz would remove baz
yum update @foo would pull in baz again, and maybe newpkg1.
In the last command, the packages baz and newpkg1 would be listed as
"Installing for dependencies" (rather then "Updating").

The above example does exactly what you want it to do, just not how you
would like it to do so, I presume.
