I've found my partially downloaded update files in /private/var/folders/<blah>/com.apple.SoftwareUpdate/<blah>
The <blahs> appear to be some hash of either the computer or the software being downloaded. Try the following:
Open a Terminal
sudo find /private -name ' SomePartOfTheDriverNameYouAreLookingFor' -print
then sudo cd <the directory shown above>
Note I don't see /private in finder because of the permissions on it (hence the need for sudo above).
Also note, I had one directory in <blah> named -Cache- which is tricky to cd into because the leading - is perceived as an argument to cd, so I just cd into the entire directory path instead.
Finally, be wary doing things as root (sudo) as you can end up damaging your OS (so don't go around removing files you are not sure about)
