I don't believe it's currently supported since I can find no mention of it, nor support for the A5 core. Let us know if you discover someone has added support for Vybrid.
Today I came across this blog post which shows how to use OpenOCD with a Kinetis L Freedom board via CMSIS-DAP firmware in the OpenSDA circuit. The Vybrid board also supports CMSIS-DAP in OpenSDA, so thus it might be possible to get it to work then with Vybrid.
