I have downgraded xorg-server before and it is not to bad. Just mask the current version and do a emerge -uvDNa world. You may have to mask a couple more packages but the error will tell you which ones they are. I was able to just mask the one tho. If you are using hal, you may have to reemerge the mouse and keyboard drivers. I find them using this: equery list xf86-input That should list the drivers that need to be reemerged. I have three.
