Need help trying to patch a driver

This is the first I am hearing of being able to do this.  My T23 has has
a problem with trackpoint drift for a while and I googled a fix in the
form of a "driver patch"  clicking on the link to me to a document with
code in it that is all.  I know I need to do something with the code but
I haven't a clue how to "patch" a driver.  I have googled the subject
and all I get are hits on pages of other driver patches available but
not a howto on how to actually patch your driver.

My question is:

1. is it possible to backup the driver you are going to patch and if so
how?  Is this as simple as a file copy?

2. How do you actually patch a driver?

3. Once the deed is done, how do you restore it if your system check out
for a night cap?

Please correct me if I'm approaching this wrongly.

Thank you in advance.
