non-free package repository.
There is a package in the Non-free repository for you. It is called amtel-firmware.
Open up MCC, and go to Software Management and then Configure Media Sources. Look to see if you have "Mirror List Non Free" and "Mirror List Non-free Updates". There should be a check mark beside each one for Enabled. If those two are not there, you need to add them with Easy URPMI. Go here -->http://mandrivausers.org/easyurpmi/index.php
I like the old interface, there is a button to select it. Enter the correct version and arch for your system. Mark the two repos you need. I did this, and it generated the following lines.
Open a konsole and as root run each command, one at a time. That will add the repos if you do not have them already.
Once the repos are added, go to install software, and search on amtel. The package should show up. Install it as you would any other package.
Note, the two repos I selected are for 2009.1 and i586 ( 32 bit system ). I sisn't take the time to pick a close to me repo, so do it for yourself, and select a mirror that is close to you.
