[HELP] Nvidia 8500 GT 1GB

[trancepharma]

I installed Retail Copy of SL following this guide;

Now, I got 10.5.5 on one drive and Windows 7 on another drive and last partition I got SL. Everything is working fine except for the graphics card. In the system profiler it shows 512 mb having NVinject 0.2.2 installed. Previously on Leo I used NVinject 0.2.1 which worked perfect. But doesn't seem to work with SL. I tried almost everything removing all NV*.* and Ge, EFI string, but to no avail. There's also a problem with OSx86 tools when I check Repair Permissions and run task it gives me error APPLESCRIPT ERROR 9900. No package found on disk and can't install KEXT via OSx86 tool (The way i usually install kext).
Any help???
Tried google a lot. Now i m left with no choice :/
My full hardware configuration;
Dg33FB Mobo
Intel c2D E4600 processor
160 GB SATA HD
Dual Layer DVD burner.
8500 GT Nvidia 1GB
On board Ethernet working perfect.

Please!!!!.....
