2wire PC Port Driver

I bought Tiger about a half a year ago, but shortly after buying it, I went online to find out that my 2wire PC Port, which I use to connect my iMac to the internet, does not work with Tiger. Everyone claimed that things were fine beforehand, but after upgrading, it wouldn't work anymore. After months of emailing 2wire and getting the response that there was no driver out for Tiger, I finally got a response from an employee with a "new" driver: http://s6.yousendit.com/d.aspx?id=1M10P1V71XX223V6V0YB755TBC

I was wondering if anyone possibly having issues with 2Wire PC Port on Tiger could try this driver out and tell me if it works. I am currently on Jaguar, and do not want to upgrade to Tiger if this driver doesn't work.

Thanks,

Adam
