Yep! when I ran:
rpm -qa | grep NVIDIA - it returned the version 3123 that Mandrake installed
rpm -e NVIDIA returned (version that mandrake installed, NOT installed?)
So, by going into Mandrake Control Center > Software Manager > Uninstall Software
I was able to get rid of it, and ANY reference of nvidia/NVIDIA on my drive I rm -f the damn thing!!!!. All is well now.
