For plugging in via hdmi, I don't know, you're going to have to troubleshoot it some more I think. I assume hdmi video was working for you just fine under 10.7? Does it still work with 10.7 with the new dsdts?
With older 10.7 installation dual monitor was ok (both vga and hdmi) but with older DSDT (in this moment i've deleted Lion installation...)
I've tested that booting in safe mode (-x at boot) make the video working properly and dual monitor works like a charm, but no qe/ci enabled... the problem is when the system loads the nvidia kext...
A little question... the DSDT edit i've suggested for disabling 9200m can replace your "z01i -> DSDT" edit?
in theory loading kext will skip the discrete card (the system ignore it)?
In this case we can try this combination for solve the problem? (if it make sense)

And now, I have QE/CI. And it looks SO. DAMN. SMOOOTH. I mean, it's on its four year now, and still running strong.
bcc9, I cannot possibly thank you enough.
can you try if dual monitor works?
Edit: the problem is generalized... that issue heppens every time the video card try to change or reset output resolution (for example when i try to change the resolution of my primary screen) thus seems to be no related to secondary output.
The good news is that when the issue happens you can solve it forcing a user logout (shift+cmd+Q then enter) and the system adjust your screens "automagically"
I Forgot to tell that i've updated to 10.8.2
EDIT2: Problem Solved
Investigating on the net for the problem i've found that it's a nvidia driver problem... it was solved with the newest drivers (that was not released for our video card)
I've Downloaded this drivers http://www.nvidia.co...f02-driver.html
then i've extracted all contents with Pacifist and putted in /S/L/E
reboot and... solved! now works like a charm! dual monitor hot plug and changing resolution without problems
