I've successfully installed Snow Leopard on an Inspioron 530 using method from Mat Tiszenkel:mat tisz.com/hacks/snow-leopard-inspiron-530.
Everything is working great, except my video card is an nVidia 9800 GT and its not being recognized. Sys Profiler says its a generic GPU w/ 32MB.
After hours of research, I think my DSDT needs to be modified to include the 9800 GT strings, but I'm not sure how exactly to do this. I did try using OSXTools to modify the plist, but I'm not exactly how the DSDT & Plist work together and thinking that the DSDT might be over-riding the change or something.
I've attached my current DSDT.aml that works perfectly except for Graphics. Can anyone direct me with the best way to adapt? Thanks!

You dont need to edit the DSDT to add graphics support you have other choices:
* Put an EFI String in your boot plist using EFI Studio.
* Use PCEFI 10.3 boot and use the built-in GraphicsInjector option.
Either one should be easier and more flexible than modding the DSDT.
Thanks for the tip. I got EFI Studio and edited my plist directly manually. I followed the directions outlined here:

Now Sys Profile is showing the card that way its supposed to and I have Quartz Extreme support. Everything appears to be working great! Hope this can be a help to others.

Is there an advantage/disadvantage of inserting gfx-information into the DSDT? Except that it's harder to edit in case you buy a new one ..
