SDA Standard Compliant SD Host Controller driver won't load in XP

I have a Dell D420 Laptop that has an SD Card slot on it. We are running XP
SP1 and I have obtained the required drivers (sdbus.inf, sdbus.sys &
sdhcinst.dll) from the Microsoft SP2 driver files.

I'm trying to do this automatically without any intervention. When
deploying a new PC, after the sysprep process, we turn on Plug and Play and
let it find the specific drivers for each PC type that we have, which is
extracted into appropriate directories on a CD. This has worked for all
other drivers, except this new SD Card on the newest Laptop that we are
getting from Dell (Latitude D420). Instead of just loading the drivers
automatically, XP prompts me for the drivers with via the New Hardware Wizard.

I can go through the wizard and point to these same drivers - it says that
they are not signed (but they're from Microsoft?!?), but I can ignore that
and continue and they will then install just fine.

How can I get passed whatever is not allowing them to install automatically?
Is it because they're not signed? If so, how can I resolve this (at least a
workaround)?

Thanks,

I tried copying the .cat file to the same directory, but that didn't work
(same result).

I then noticed that I had the same SD Host driver in another directory (for
another model of Dell PC), so I got rid of the duplicate driver (now, there
is only one driver) - wondering if it was prompting me to choose which driver
to use. Well, the New Hardware Wizard still prompts me to find the driver.
But, this time, when I choose "Next" (to search for the drivers - the default
setting), it finds and installs the driver, only prompting me to choose
"Finish".

Why won't it automatically find and install the drivers like all of the
other drivers?

Any other ideas?

We are starting to deploy SP2 within our environment, but we do have one
internally developed application that conflicts with SP2. This application
is scheduled to be upgraded (to be compatible with SP2) by the end of this
year (if it happens by then ;-).

In the meantime, I need to continue developing solutions on our XP SP1 clone
image.
