Mac OSX Lion on Lenovo H310 - USB Mouse Jittery using nVIDIA GeForce 8400GS

Hello guys, please help me to solve this problem:


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


I've using it on my Acer ASPIRE M1800 PC (nForce 630i Chipset with DualCore CPU E5200 @ 2.5 GHz, 2 GB RAM DDR2, 2 x 320 GB SATA HDD, DVD-R/W Dual Layer) and everything work fine with iATKOS L2 (Mac OSX Lion 10.7.2 - Upgraded to 10.7.3). With just adding my Device ID to NVDANV50Hal.kext on S/L/E and boot with "arch=i386 Graphics Enabler=Yes" ... all accellerations and resolutions work OOB fully Q/E & CI.


But now, I found some problems when using it on my new PC with this specs:


Vendor : Lenovo H310 Desktop PC

Chipset : Intel 82801G SounthBridge

Processor : Intel DualCore CPU E6700 @ 3.2 GHz

VGA : OnBoard Intel G41 (detected as unknown 64 MB on Snow Leo 10.6.2 & Lion 10.7.2)

HDD : Western Digital @ 500 GB, SATA-7200 RPM

Memory : Samsung 2 GB DDR3 Single RAM

Others : Lenovo 18" LCD Monitor, DVD-R/W, Realtek OnBoard Ethernet, Card Reader, PS/2 Keyboard & USB Mouse.

Misc : No AHCI Mode on BIOS (but just IDE), VT Tech, Video Mode Switch (between Onboard & PCI-e)


The installation succeeded; iATKOS L2 DVD using the OnBoard VGA.

Some problems occur when I decided to replace the OnBoard VGA with my 8400GS PCI-e. All accelerations & resolutions work fine with fully Q/E & C/I (just a same as above method), but wait... now i get very slow OS Performance and unfortunately my PS/2 Mouse & USB Keyboard couldn't run perfectly (jittery, acceleration problem, I couldn't move it on). Then, I try to replace the USB Mouse with PS/2 Port, using other mouse / keyboard but it doesn't work anymore. When using OnBoard VGA (1024x768 Native Resolution; X4500.kext compatibility issue, no Q/E & C/I) it works perfectly (Both PS/2 Keyboard & USB Mouse).


So, I assume that 8400GS VGA caused this problem.

(Additional: When booting with "-v" option, I got some outputs that ALPSGlidePoint, VoodooPS2SynapticsTouchPad, and ApplePS2Trackpad are loaded. I don't know what this mean, since I'm sure that my PC doesn't have this hardware. I've tried to remove it from S/L/E, but I found nothing there...!?)


Please, help me to fix this problem... Thanks very much, and I apologize for my bad English.
