Windows 7 Install on Inspiron 9300--Drivers?

Decided to try Windows 7 on my 9300 laptop. So far, pretty good. Performance is fast, but I need a few drivers I can't find: 1. The multimedia audio driver (no sound).  Any ideas where a Vista driver could be found? 2. Can't get the correct resolution on my display with the standard VGA driver in Win 7.  ATI is no help; can't find a Dell driver for Vista for the X300 mobile display adapter. 3. Touchpad only works for moving the mouse pointer; the scroll bars don't work. I assume I need a newer Vista driver for the touchpad software.   Any suggestions are appreciated!

Thanks, but this answer came 3 YEARS after the question.  Resolved long ago... Windows Update actually offered an update for the X300 which worked fine.

x300 must use the Legacy drivers.  vista drivers would work but only for 32 bit windows.  64 bit windows REQUIRES WHQL certification or  it wont load.  Also the directx 9 is not in win7.  You have to install Directx June 2010 patch run DXSETUP.EXE.

The video driver is this one.  Download  Windows Vista 32-bit
