I know that Emory/Goizueta is now allowing students to submit GRE scores instead of GMAT scores. They have a good one-year program. I also believe that Babson is starting to accept the GRE rather than GMAT - you should check with them directly, though.
However, compared to Europe, one-year MBA programs are still a rarity in the US. The best ones (Kellogg, Cornell, Goizueta, Warrington) - are going to need you to submit a GMAT score to apply.
