If you have the source rpm then you can rebuild it for the newer kernel, otherwise you may be out of luck unless you can find a copy of it on another website. I spent the $15 for my license, but only because I felt like helping them out. The last rpm that I used before this worked flawlessly, it just didn't have all the V.92 modem support yet - but as a regular V.90 it worked great
. If & when I upgrade my kernel I hope I don't have any issues with the new driver.
