I want to downgrade systemd from 207-r2 to 204 (highest stable).

OK. So I need to downgrade virtual/udev to 200.
I thought
emerge -1 =virtual/udev-200 =sys-apps/systemd-204
would do it. But this failed (see below) and suggested masking
might help.
So I added package.mask/systemd, which contains
=virtual/udev-201
=sys-apps/systemd-205
and then issued the same emerge as above.
But this also failed (see below).
What incantation do I need?
thanks,

[blocks B ] sys-apps/systemd (sys-apps/systemd is blocking
sys-fs/udev-207)
[blocks B ] sys-fs/udev (sys-fs/udev is blocking
sys-apps/systemd-207-r2, sys-apps/systemd-204)
These conflicts are often so confusing that I emerge -C both of the
blocking packages and then re-run the emerge that I really want.
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.
Right, thanks. Note that sys-fs/udev is not on my system, the conflict
occurs because portage wants to emerge it. I am trying to downgrade the
virtual udev.
I tried your suggestion as follows
* quickpkg'ed
sys-app/systemd virtual/udev sys-app/gentoo-system-integration
* unmerged all three
* merged the desired virtual/udev version with --nodeps
(it wouldn't work without --nodeps)
* tried to emerge the desired versions of the other two
(without using --nodeps)
This last step fails because it seems (assuming I am reading the emerge
tree output correctly, see below) that dev-libs/lubusbx-1.0.17:1 requires
virtual/udev-206.
But I don't see that version dependence in the ebuild. Moreover this is
the only version of libusbx in the tree so (again assuming I am reading
the tree correctly) this says that gnome 3.6 requires
virtual/udev-206-r2, which seems strange. Indeed, canek has said that
gnome has trouble with systemd-206 (which virtual/udev-206 would bring
it).
So I did the emerge -K you suggested and am back where I started.
Any help would be appreciated.
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 :)
I am hoping not to have to do that (or emerge --nodeps).

livecd package.mask # emerge -1 --ask =sys-apps/gentoo-systemd-integration-1
=sys-apps/systemd-204
These are the packages that would be merged, in reverse order:
