Are ConnectX-3 VPI adapters compatible with the Red Hat MRG (i.e. real-time patch)?

I would like to use the ConnectX-3 VPI adapters on a Scientific Linux system with the real-time patch instaled.  This is functionally equivalent to a RHEL system with Red Hat MRG.  Has anybody successfully used these adapters on a Linux system with the real-time patch installed?

Thanks,

Malcolm Smith
