I only have one suggestion. If you know a web link for the driver
you're looking for, you can use web.archive.org to find an archived
copy. When you look up a link, it shows you all the dates of the
backup copies it made. Archive.org has at least 5500 1TB hard drives
to store stuff on.
For example, I can see files listed here, but clicking a link
didn't give me the file.
http://www.la.viewsonic.com/la/soporte/drivers.htm
If I take one of the links and look it up on archive.org, this
is what I get. I clicked the most recent one, to download it.
http://web.archive.org/*/http://www....s/vs_winxp.exe
That file looks like an InstallShield, so I can't burrow inside it
and tell you whether the V95 INF is in there or not.
You don't have to use the search dialog on web.archive.org. Just
build a URL manually, by tacking the desired URL, onto the end of...
http://web.archive.org/*/
The asterisk is a wild card, asking for a match on any date, which is
why a page full of dated links shows up.
web.archive.org doesn't have everything. And the software on the site,
has to "rewrite" difficult web pages, to make them work. And that fails
to work properly... frequently. So the archive is not a "precision
instrument". But it has found useful stuff for me, more times than
I can count.
If a target web site has an exclusionary robots.txt file, then archive.org
won't archive it.

With respect to your original question, I've had problems like that
too, where there is some cruft in the registry preventing video
settings to change. But if the setting isn't in plain English,
I can't find it using regedit. The problem is figuring out
where that is stored.
