Install TXTSETUP driver in installed Win XP, w/o device present?

This is an ultra-expert level network administrator question. If no one can
answer this I will not be surprised, because I have gone for years without a
good solution. There are no answers on the web. I have looked fairly
thoroughly.

This is a very common problem for large schools and businesses who make
(ghost / ImageX) disk images and need to prepare the disk image from an
existing computer model to work on some new brand of computer coming in the
door.

,

If the existing disk image HAL is compatible with the new incoming machine
(and they are pretty much all compatible, now that Intel standardized its
processor line) then really the only thing standing in the way of loading an
existing XP OS image on a new computer is the installation of device drivers
for whatever type of disk controller is in the new machine.

So, I just want to load in the 500 kilobytes worth of TXTSETUP.OEM device
drivers for the new disk controller. I should be able to preload it into an
existing installed Windows XP computer via Add Hardware or something right?
No, wrong. There is apparently NO WAY to do it.

This turns out to be really really REALLY hard. Practically impossible for
all I can tell. A set of TXTSETUP.OEM drivers is tiny, a handful of maybe six
files but there seems to be no way whatsoever to preload / add it into the
disk controller driver database of a machine that has Windows XP already
installed on it.

I think that forcing people to insert their Windows OS CD, booting from it,
choosing "Repair Windows" and then only being able to install this new disk
controller driver from a floppy in the "Text Setup" part of the Windows
repair process is WAY OVER THE LINE in terms of ridiculous and unnecessary
complexity.

But I have had to do this dozens of times in the past to make an existing
and fully working Windows XP disk image to work on a new machine that is
missing only these 400 kilobytes of disk controller drivers to boot the
machine.

There has to be SOME simple way to preinstall TXTSETUP disk controller
drivers, but right-clicking on the INFs in the file collection and choosing
"Install" doesn't do whatever is required.

So what is the answer here? There must be a fairly simple way to do what I
need.
