Upgrading to current xorg-x11-server-Xorg in rawhide causes this error to be printed when attempting to start the server with the openchrome driver: "dlopen: /usr/lib/xorg/modules/drivers/openchrome_drv.so: undefined symbol: resVgaShared". Downgrading to older xorg-x11-server-Xorg fixes the problem. I'm filing this bug under openchrome rather than Xorg because I suspect what's wrong here is that openchrome needs to be recompiled to take into account changes in Xorg.
Hello!? Openchrome has been broken for at least two weeks now. We're in the middle of an alpha cycle! People with openchrome display adapters can't test F12 alpha! You can't release F12 with openchrome broken! Please fix!
Sorry for the late answer, took a couple weeks vacation. I guess a rebuild is not enough and the driver probably needs to be patched. I'll take a look asap. Feel free to beat me to it, patches welcome.
Should be fixed with http://koji.fedoraproject.org/koji/taskinfo?taskID=1633383
