To use PS2 keyboard you need ApplePS2Controller or VoodooPS2Controller kext.
Apple uses USB or bluetooth keyboards, so yours needs a driver.
About WiFi, it appears that AR5B225 is not supported (didn't try).
You may try DSDT fix.
Otherwise here is a list of supported cards: http://forum.osxlati...cards-inventory

Let me know which extensions are installed on your system.
It is always better to install vanilla OSX, do not use any installer.
To start you just need FakeSMC and keyboard extensions.
