I have that already and still nothing just. Black screen, and I'm using chimera 1.9.1 latest
we have the same gpu card .. mine works with no problem under 10.6 - 10.7.3 everything apps works smootchies. Just install latest chameleon bootloader .. put "GraphicsEnabler=Yes" in org.chameleon.Boot.plist .. that all .. U should disable Integrated onboard intel GPU by your motherboard bioses

<key>UseNvidiaROM</key> <string>Yes</string> <key>VBIOS</key> <string>Yes</string>to your ...Boot.plist
download the ROM from post #431 rename it to your ID if needed.
If that dosen't work u can try it with the NVIDIA Drivers for 10.7.3.
A method which will work 100% is to use the kexts from Snow <10.6.2:
AppleGraphicsControl.kext/ DSACL.ppp/ DSAuth.ppp/ DVFamily.bundle/ GeForce.kext/ GeForce7xxxGLDriver.bundle/ GeForce8xxxGLDriver.bundle/ GeForceGA.plugin/ GeForceVADriver.bundle/ NVDANV40Hal.kext/ NVDANV50Hal.kext/ NVDAResman.kext/

I suggest you to reinstall the lion with the USB chameleon method, and setup to boot with an external video card if it is available...at bios

I installed on my PC kakewalk lion 10.7.2
Installation gone good until the end, but i have problem with black screen in HDMI.
6 gb ram
1 asus engts250 dark knight dvi-i x 2 (i have only 2 dvi connector)
and i have 2 monitor 24'' samsung (vga or hdmi )
I buyed 2 cable DVI-I-> HDMI and in other system i use this in HDMI MODE both.
This is my step:
i prepared USB Stick with Kakewalk 4.1 (using dmg of lion)
Installed 10.7.2 and 10.7.3
All is OK:
i installed nvidia 700.xx driver for my card (from nvidia site)
If i restart pc.. and i connect 1 DVI->VGA, computer star normaly... i have full support (Acceleration, FULL HD resolution)
If i connect 1 monitor in HDMI .. all freeze.
if i connect hdmi before start.. after APPLE logo, i get black screen.. all monitor shutdown and pc continue to work (i tested opening DVD slot with key in keyboard and work).
So i think is problem of "dvi-I -> HDMI" connection.
i tested many solution in this forum.. i tryed to load "FROM ROM file" extracted from my videocard..
Used old driver nvidia..
Only VGA work for me, if i connect HDMI is black screen.
In verbouse mode he stop after DSMOS is Arrived..
NV****50HAL.kext is the last message i see in monitor. Monitor instead show me "login screen" show me "black screen like i remove power to monitor and they go sleep.
I don't care to have "HDMI for audio", but i need to have in HDMI video signal.. cause i don't want to change cable connected to my computer everytime i need OS X.
Is possibile to get HDMI working?
I tested Efi string with Efistudio too, NVENABLER and NVINJECT...
All the rest in pc work good.. (sound, ecc..)
This method i need again to test.. today i try..
I not undestand again why.. after many hours i work in macos.. and restart windows system... the "date" is locked...
For example yesterday when i started windows instead of 00.00 i got 9.00...
