Glad to find this thread. Sounds like a similar problem i'm having trying to get dual monitors working.

I have the DVI to DVI on my primary monitor. As soon as I plug in the HDMI to my second monitor the system hangs.
When its plugged into HDMI the system hangs on boot up as well.

Do you know if my second monitor will work if i get a HDMI2DVI adapter and plug that into the DVI port on the second monitor?

I think the root cause is with HDMI, and I probably need some dsdt edit or kext?
I've read posts that nvenabler had some effect, but I can't seem to find that in the latest multibeast; i'm also on yosemite.

Any help with getting that second monitor up is appreciated.

Thanks!
