The Workstation default installation contains the glibc.i686 package, presumably a dependency of xorg-x11-drv-geode. I doubt this is intentional. Perhaps xorg-x11-drv-geode is listed somewhere as part of the x86_64 compose? The AMD Geode product line isn't x86_64-capable, so a driver for it does not make sense.
workstation includes the base-x group, which in turn includes xorg-x11-drv-geode So, perhaps we should just drop it from the base-x group now?
We are going to try and make it optional and see if that fixes it. ;) https://pagure.io/fedora-comps/pull-request/1
This is fixed. ;) Thanks for pointing it out.
