Okay, so I got my ethernet working finally, updated to 10.5.4 and now all I need is Audio and WiFi

Here is my WiFi:
06:09.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller [10ec:8185] (rev 20)

And Audio:
00:10.1 Audio device [0403]: nVidia Corporation MCP51 High Definition Audio [10de:026c] (rev a2) Really is a Sigmatel 9200

Any help would be appreciated!
