Well, let's go troubleshoot.

First, for initial boot a.k.a installation, use essential kext only. Lilu, Whatevergreen, VirtualSMC (and SMCBatteryManager), VoodooPS2Controller are the needed ones.

Use USB Mouse is simpler than enable the I2C Touchpad. But, if you want to try, here's the trial:

Add VoodooI2C and the satelite (I assume your stelite is HID). So add, VoodooI2C and VoodooI2CHID.

Add SSDT-XOSI to OC/ACPI

Add ACPI Patch : _OSI to XOSI (select from patch dropdown menu).

On this state, your touchpad should work like mouse with click.

Note:

Some of VoodooI2C kexts may won't work even the setting is correct. You have to try the other version.

Prelinked Kernel would make VoodooPS2 and VoodooI2C crash on some device. Take a look into both kext, if there are VoodooInput on both kexts, better eliminate one of them. I recommend to use older VoodooPS2Controller which doesn't have VoodooInput on it's Plugin. And, you could delete the other plugin and only left VoodooKeyboard only. Keep the VoodooI2C and it's kexts untouched.
