Hi
Dave Jones summarised the problems at http://www.livejournal.com/users/kernelslacker/27433.html
Hope this helps,

I've got kernel.org 2.6.15.1 running fine on a couple of FC3 boxes. No problems the I've detected, but there's nothing exotic about the configuration, just a couple of vanilla Dell boxes.
It wouldnt be wise to depend on one user experience to push a new major kernel release into Fedora especially when it goes into a community maintained Fedora legacy project.
