In your particular case, if you actually remove both of those packages your machine will not be bootable until you successfully emerge the older versions (obviously) so I strongly recommend using quickpkg to save both packages before removing them. Then, if the worst happens and you can't install the older versions you can re-install the saved binary packages with emerge -K. Another officially unapproved workaround I use when really frustrated is to bypass "emerge" completely and do this instead: #ebuild /usr/portage/sys-apps/systemd/systemd-204.ebuild merge Sometimes it works :)
