Please, somebody help me...!

I have ZOTAC nVIDIA GeForce 8400GS @ 512 MB DDR3 64-bit PCI-e VGA.

Using Mac OS X Snow Leopard 10.6.3 - Lion 10.7.3 on my Lenovo L-IG41C1 Mobo with Intel 82801G Southbridge ICH7 the Q/E & C/I work perfectly by using modified NVDANV50Hal.kext.., but my USB Mouse "jittering, leak, I couldn't move it on and then my System freeze"...!? If I'm using the G41 OnBoard VGA (x4500); my System work fine with no Q/E & C/I.

So, I assume that Graphics Power Management for my PCI-e caused the problem.
Please, somebody generate & build this one for my 8400GS PCI-e VGA...

Thanks & regards.

BTW, with same VGA but other CPU Chipset, it run perfectly with no problem (on my nForce 630i for example).

Some problems occur on my Lenovo G41 Mobo. I've using a lot of methods from many forums to fix this problem; modify xxx.kext, EFI String, Natit, but nothing work.

But, someone on another forum say that:
"...if you're experiencing slow performance with any nVidia card (namely the Quadro and Fermi platforms) just disable/remove the AppleGraphicsPowerManagement kext in /S/L/E/ and you'll see that you'll write to disk less (??? I have no idea why) and you'll also have a bunch more free RAM."

What do you think about this, should I remove my AGPM to the trash...!? Thanks and regard...
