Thank You for all your hard work.

Is there really a reason to upgrade to fc4? I have fc3 right now and it's 
doing good.

So... same kernels are now available for fc4 in the "planetedge"
repository (ie: add a line with planetedge instead of planetcore
in /etc/apt/sources.list.d/planetccrma.list)

Then "apt-get update" and...
