Oh, I guess I found the wrong driver. I don't think there is a newer driver available for your laptop on the AMD website, or on Compaq's support website. The network driver update certainly won't make MTA run (but it doesn't hurt to update, anyway), so I believe you're out of luck. Your laptop simply cannot run MTA, to the best of my knowledge. If you can track down some RAM to add to your laptop, it might work, but that's just a guess. Sorry!
