It would be a great help if the kernel src rpm's included the .config file used to build the associated kernel rpm. With the vastly increased options in the 2.2.x series, having to go through every option to select sensible choices can be a bit of a pain. Especially since the kernel doesn't compile with the defaults (first Starbuck release). You should really be able to re-create the kernel as supplied by just following the usual build procedure. I'm sure this would also reduce the problems newbies experience when first recompiling the kernel.

That configuration is always part of every src rpm. We also always build kernels by doing rpm --rebuild kernel*.src.rpm
