OH!! I didn't actually download ndiswrapper from that link, so I had no clue. I found a guide on how to enable an external repository that contains an rpm for ndiswrapper.
sudo rpm -ivh http://rpm.livna.org/livna-release-6.rpm
sudo rpm --import http://rpm.livna.org/RPM-LIVNA-GPG-KEY
yum install ndiswrapper
and try that. as for whether or not I'll like fedora, well I downloaded the live cd. We'll see how it goes, but I've never had anything but trouble with a distro that uses RPM as its package management solution.... just never seemed to agree with my laptop. I'm using Arch right now, and I love it: however you have to do a TON of manual configuration.
anyways, let me know if you can install ndiswrapper
