I am able to install this , and get an updated driver off windows update.
HOWEVER, in device manager, I see this message with a yellow "!"

This device is not working properly because Windows cannot load the drivers
required for this device. (Code 31)

Click 'Check for solutions' to send data about this device to Microsoft and
to see if there is a solution available.

Any ideas how to fix this?

I have the same problem.
 
I figured out the problem. I have the Inspiron 6400, so your mileage may vary.

When I updated the device Ricoh SD Bus Host Adapter (under SD host adapters
in device manager) it messed up the Ricoh MMC Host Controller. So I went to
device manager and rolled back the latest version for the SD bus Host Adapter
(I am now using version 6.0.5384.4 dated 6/21/2006) and the problem was
fixed.

So the MMC controller device driver wasn't really the problem. It was just
the symptom.

Hope this helps.
 
I fixed it. Here is what you need to do:

In device manager find the device Ricoh SD Bus Host Adapter and roll back
the driver to the previous version. I am running the version dated 6/21/2006.

Worked like a champ, and now my built-in memory card works.
