Recently i had a problem with my laptop and Win7, and i did a little research for uninstallations here's some tips:
On the Registry here's the KEY were you can find the uninstalls strings:
HKLM\Software\microsoft\windows\currentversion\uninstall
You will find some folders and inside each the corresponding application and uninstall strings ;)
One of the applications that microsoft gives for uninsttaling drivers is "dpinst.exe"
If you need to look at the install or uninstall log, goto
c:\windows\dpinst.log
That's it, just another quick tip.
