Noob learning DSDT fix. need help from pro.

[Thong85353]

HI.
I'm trying to learn how to create my own DSDT if possible. i'm a noob, so there would be lots of things I need to learn. Anybody who can help, please do, I'm appreciated for all your efforts. This is what I did to learn from it.
I dumped a fresh dsdt.aml using Linux, and started from there. So my question is what fix(es) should I do from a fresh dumped from linux ubuntu 9.04. Thanks.
