HiJason, nice to see another member of the "reality-based community" here in EP.
I'm not connected with UTEP directly, although my SO is a professor in the anthropology dept. I'm seriously considering entering a graduate program there in the next year or so, so I'm also interested in whether there are any atheist student organizations.
Incidentally, atheists in the EP area might be interested in checking out the Unitarian Universalist church, at 4425 Byron St. I'm a member, and the congregation is probably 30% or 40% atheist. I'm doing a talk entitled "Atheist Spirituality" there on August 16; hope I can find something coherent to say :-)
