iPC OSx86 10.5.6 Graphics Problems

[schismatic]

My iPC OSX 10.5.6 installation with patched iso to PPF2 worked fine. My
system is:

ASUS M2N32SLI-DELUXE -nForce 590i MCP55 Chipset
AMD Athlon X2 4800+
2GB RAM
XFX nVidia 6800GT 256MB
Realtek 8187
USB mouse and keyboard.

My issue:

I install OSX without the graphics card using Voodoo 9.5.0, Seatbelt.kext
10.5.5, Patched USB Driver, NFOrceATA Test driver for the chipset. I get no
problems with my setup other than the fact that I do not have a graphics
driver installed so no graphic acceleration.

I then try to install a graphic driver. I have tried many different
methods: First I used OSx86Tools to download and install a driver for my
card. Upon installation and reboot, I am left with a very very slow mouse.
If I move my mouse, the cursor takes about 3 seconds to respond on screen -
it is basically unusuable. I then read somewhere that the NVdarwin 256mb
driver might work with my card. I did a whole reinstallation of the system
with this selected. Again, once I had booted into OSX, I got the slow mouse
issue - this basically is making the OS unusable from a practical point of
view.

I then read on nvinstaller.com that injectors did not work with 10.5.5
drivers which I assume also applies to 10.5.6. They suggested that I
installed the 9f23installer.pfg package drivers and to then use EFI Studio
to add my device and then write the hex code to com.apple.Boot.plist. This
did not however work and I was left with a system where the mouse wasn't
working again.

This issue does not affect the USB keyboard. I would like to try a PS/2
mouse on my system but I have not had any luck getting one be recognised,
even though I have installed the PS/2 drivers in the OSX installation.

Any pointers or help regarding this issue would be very grateful.

Keep up the excellent work, it is well appreciated!
