Resolution problem on D630

[voonwah]

Good day to all. I have a little problem after i installed Mac OS SL Universal 3.6 and found that all hardware is working like a charm except resolution unable to maximize to 1440x900 (current is only up to 1024x768). I'm quite new to this,can anyone actually guide me how to install extra kext for the display (Nvidia NVS 135M)?

Tried kext pack for DELL D620/630/830 and end up with kernel panic and reinstalling SL 10.6

Thanks in advance and really appreciate if any Mac guru can help in this.
