OK, after a lot of digging I found the Mac drivers for this monitor, to be used with the HP probe (the eyeOne display2 does NOT work).
It is frustrating that this was nowhere to be found on either HP or X-rite's sites; you can't actually find it! And don't even bother with HP technical support -- they told me this product didn't exist. I think I googled some search terms like "help me find this *&% app already" and on page 1000 I found the link.
I'm using the DreamColor with an HDLink box, which is being fed the single channel HD-SDI out of a Kona LHe. You calibrate with direct DVI connection to the computer (make sure the probe is connected to the USB on the monitor), and it holds that calibration when you unplug the Mac and plug in an HDLink. I did find the white point point a little red (anybody else?), so pulled back on the red gain a little of the 1D LUT in the HDLink.
