I have had OSX 10.5.8 (Vanilla) IPC working on it for months now but still cant get thes working below, can anyone help?

1) Firewire - does not recognise a thing, hard drives or Sound cards?

2) Media Card Reader - Crashes when the Kext is added and card inserted?

3) VGA out - Blank screen when a monitor is attached? (Using NVdarwin 128 Kext - QE/Ci all working but no shutdown or sleep)

4) No Battery monitor or alert?

Are there any tips or hints when using this laptop (Has the NVidia 8400GS Graphics) with OSX in the way of what best kexts to use?

I have scoured the net and forums but there isnt anything specific to my IPC Vanilla install and hardware
