Vista Business 64bit drivers for Dell Inspiron

So, I just installed Vista Business 64 bit on my Dell Inspiron 6400. However, I didn't realize that Dell didn't have any drivers for 64bit Vista. Can someone help me out? I know a lot of people have been having this issue as it's all over Google searches I have made, but I can't seem to find any recommendations on what I should do to fix the problem. Can someone point me where I need to go please to get these drivers? Mainly I just need the touchpad drivers and ATI mobility drivers. I tried the touchpad drivers from the synaptics website, but they didn't install for some reason and ATI does not release any 64bit mobility drivers yet, they say you should get them from the manufacturer of the laptop. Help?

Ok nevermind, I found a hacked up 7.10 driver that works for the mobility cards and figured out how to get the synaptic pad driver to work. Not sure what the problem was with it but it all works now. Thanks anyway guys. I'm sure I'll be back with more questions since I'm sure there will be plenty with this new OS.
