Vista to Xp Change - Driver Problems

Let me start off by saying I have an HP Pavilion dv5-1000us laptop computer. I recently changed the OS from Vista to XP. As expected I'm having some driver problems. I really don't care about the touch screen quick launch bar not working, and trivial stuff like that. But my wireless card will not work. NO wifi whatsoever. I got a realtek driver that works fine for the ethernet, but not the wireless. Any ideas?

Any help will be greatly appreciated. thank you

also: if anyone knows of any other drivers or software that might make this massive hardware - software conundrum a little easier I would appreciate it. thanks.
for example: the quicklaunch bar
