Chuck:
Thanks. My OM-TTL - compatible flashes are Braun and Sunpak 433D. I'll have to
look to see what the feet are like. The Braun has a low trigger voltage and I
can put a generic foot on it but the output is not adjustable. The 433D seems
to have a trigger voltage below the 24V limit on the OM-D and has the advantage
that the output can be adjusted.

If you look at the bottom of a T-32s foot you'll see that there is a plastic
cam between the two non-triggering contacts. This cam lifts those contacts off
the surface of the foot. Then, if you look at an OM flash shoe designed for
TTL flash you'll see that it has a recess in the front for the contact lifting
cam to drop into. That sets the contacts back down onto the appropriate
electrical contacts in the shoe.
So, when you place a T-32 into a foreign hot shoe the flash's electrical
contacts don't actually make contact except for the center trigger contact.
But I have used Sunpak flashes with OM TTL module on my Canon 5D with no
trouble despite the fact that the Sunpaks don't have the lifting cam. I had no
qualms about using the T-32 in the E-M5. But I'm not sure about the Canon
540-EZ.
BTW, getting flash sync at 1/320 vs 1/250 was a nice bonus.
